Normally it doesn't matter if we show the pre-image or th post-image
for the common parts of a diff because they are the same. If
white-space changes are ignored they can differ, though. The
new text after applying the diff is more interesting in that case,
so show that instead of the old contents.
Note: GNU diff shows the pre-image.

The "--xhtml" option is supported only in highlight < 3.0. There is no option
to enforce (X)HTML output format compatible with both highlight < 3.0 and
highlight >= 3.0. However default output format is HTML so we don't need to
explicitly specify it.

The hints in the current "instruction sheet" template look like so:
# Rebase 3f14246..a1d7e01 onto 3f14246
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x <cmd>, exec <cmd> = Run a shell command <cmd>, and stop if it fails
#
# If you remove a line here THAT COMMIT WILL BE LOST.
# However, if you remove everything, the rebase will be aborted.
#
This does not make it clear that the format of each line is
<insn> <commit id> <explanatory text that will be printed>
but the reader will probably infer that from the automatically
generated pick examples above it.
What about the "exec" instruction? By analogy, I might imagine that
the format of that line is "exec <command> <explanatory text>", and
the "x <cmd>" hint does not address that question (at first I read it
as taking an argument <cmd> that is the name of a shell). Meanwhile,
the mention of <cmd> makes the hints harder to scan as a table.
So remove the <cmd> and add some words to remind the reader that
"exec" runs a command named by the rest of the line. To make room, it
is left to the manpage to explain that that command is run using
$SHELL and that nonzero status from that command will pause the
rebase.
Wording from Junio.

These variables should generally not be set in one's
environment, but they do get set by rebase, which means
doing an interactive rebase like:
pick abcd1234 foo
exec make test
will cause false negatives in the test suite.

fast-import: treat filemodify with empty tree as delete

Normal git processes do not allow one to build a tree with an empty
subtree entry without trying hard at it. This is in keeping with the
general UI philosophy: git tracks content, not empty directories.
v1.7.3-rc0~75^2 (2010-06-30) changed that by making it easy to include
an empty subtree in fast-import's active commit:
M 040000 4b825dc642cb6eb9a060e54bf8d69288fbee4904 subdir
One can trigger this by reading an empty tree (for example, the tree
corresponding to an empty root commit) and trying to move it to a
subtree. It is better and more closely analogous to 'git read-tree
--prefix' to treat such commands as requests to remove the subtree.

When you give a non-existent branch to git-rebase, it spits
out the usage. This can be confusing, since you may
understand the usage just fine, but simply have made a
mistake in the branch name.
Before:
$ git rebase origin bogus
Usage: git rebase ...
After:
$ git rebase origin bogus
fatal: no such branch: bogus
Usage: git rebase ...

In the case of a ref/pathname conflict, checkout will
already do the right thing and checkout the ref. However,
for a non-existant ref, this has two advantages:
1. If a file with that pathname exists, rebase will
refresh the file from the index and then rebase the
current branch instead of producing an error.
2. If no such file exists, the error message using an
explicit "--" is better:
# before
$ git rebase -i origin bogus
error: pathspec 'bogus' did not match any file(s) known to git.
Could not checkout bogus
# after
$ git rebase -i origin bogus
fatal: invalid reference: bogus
Could not checkout bogus
The problems seem to be trigger-able only through "git
rebase -i", as regular git-rebase checks the validity of the
branch parameter as a ref very early on. However, it doesn't
hurt to be defensive.

The original intention of --work-tree was to allow people to work in a
subdirectory of their working tree that does not have an embedded .git
directory. Because their working tree, which their $cwd was in, did not
have an embedded .git, they needed to use $GIT_DIR to specify where it is,
and because this meant there was no way to discover where the root level
of the working tree was, so we needed to add $GIT_WORK_TREE to tell git
where it was.
However, this facility has long been (mis)used by people's scripts to
start git from a working tree _with_ an embedded .git directory, let git
find .git directory, and then pretend as if an unrelated directory were
the associated working tree of the .git directory found by the discovery
process. It happens to work in simple cases, and is not worth causing
"regression" to these scripts.

New test helpers:
- setup_repo, to initialize a repository or gitfile pointing to a
repository, with core.bare and core.worktree set as specified;
- try_case, to run setup from a given directory and validate the
result, with GIT_DIR and GIT_WORK_TREE set as specified;
- try_repo, to initialize a repository and call "try_case" from the
toplevel and a subdirectory;
- run_wt_tests, to run a battery of tests that check for sane
behavior when GIT_WORK_TREE is set to various positions relative to
the .git dir and cwd.
Use these helpers to make the test shorter, less repetitive, and (one
hopes) easier to understand and modify.

On Windows, bash stores absolute path names in shell variables in POSIX
format that begins with a slash, rather than in drive-letter format; such
a value is converted to the latter format when it is passed to a non-MSYS
program such as git.
When an expected test value is constructed, it must contain the value that
will be produced by git, which will be in the drive-letter format. But
TRASH_DIRECTORY is in POSIX format. Fix this by using $(pwd), which
produces drive-letter format since 4114156a (Tests on Windows: $(pwd) must
return Windows-style paths).
The change in t1510 is a straight seach-and-replace, except for the first
hunk of the diff.

The current treatment of "git reset --keep" emphasizes how it
differs from --hard (treatment of local changes) and how it breaks
down into plumbing (git read-tree -m -u HEAD <commit> followed by git
update-ref HEAD <commit>). This can discourage people from using
it, since it might seem to be a complex or niche option.
Better to emphasize what the --keep flag is intended for --- moving
the index and worktree from one commit to another, like "git checkout"
would --- so the reader can make a more informed decision about the
appropriate situations in which to use it.

The errno check added in commit 3ba7a06 "A loose object is not corrupt
if it cannot be read due to EMFILE" only checked for whether errno is
not ENOENT and thus incorrectly treated "no error" as an error
condition.
Because of that, it never reached the code path that would report that
the object is corrupted and instead caused funny errors like:
fatal: failed to read object 333c4768ce595793fdab1ef3a036413e2a883853: Success
So we have to extend the check to cover the case in which the object
file was successfully read, but its contents are corrupted.

Instead of stripping space characters past the beginning of the
line and overflowing a buffer, stop at the beginning of the line
(mimicking the corresponding fix in remote-fd).
The argument to isspace does not need to be cast explicitly because
git isspace takes care of that already.

Some sites may not want to have a logo at all.
While at it, use $cgi->img to simplify this code. (CGI.pm learned
most HTML4 tags by version 2.79, so this should be portable to perl
5.8, though I haven't tested.)

The default function name discovery already works quite well for Perl
code... with the exception of here-documents (or rather their ending).
sub foo {
print <<END
here-document
END
return 1;
}
The default funcname pattern treats the unindented END line as a
function declaration and puts it in the @@ line of diff and "grep
--show-function" output.
With a little knowledge of perl syntax, we can do better. You can
try it out by adding "*.perl diff=perl" to the gitattributes file.

It happens that closing file descriptor fails whereas the blob is
perfectly readable. According to perlman the reasons could be:
If the file handle came from a piped open, "close" will additionally
return false if one of the other system calls involved fails, or if the
program exits with non-zero status. (If the only problem was that the
program exited non-zero, $! will be set to 0.) Closing a pipe also waits
for the process executing on the pipe to complete, in case you want to
look at the output of the pipe afterwards, and implicitly puts the exit
status value of that command into $?.
Prematurely closing the read end of a pipe (i.e. before the process writ-
ing to it at the other end has closed it) will result in a SIGPIPE being
delivered to the writer. If the other end can't handle that, be sure to
read all the data before closing the pipe.
In this case we don't mind that close fails.
