Linked checkouts are known under the name worktree, now. Rename the test
accordingly.
Specifically, this avoids the confusion that t2026 is actually not about
pruning in or with linked checkouts aka worktress but about pruning
worktrees, i.e. about "git worktree prune" rather than "git prune".

In addition to approxidate-style values ("2.months.ago", "yesterday"),
consumers of 'gc.*expire*' configuration variables also accept and
respect 'now' ("do it immediately") and 'never' ("suppress entirely").

Now that git-worktree no longer relies upon git-checkout for new branch
creation, new worktree HEAD set up, or initial worktree population,
git-checkout no longer needs intimate knowledge that it may be operating
in a newly created worktree. Therefore, drop 'new_worktree_mode' and the
private GIT_CHECKOUT_NEW_WORKTREE environment variable by which
git-worktree communicated to git-checkout that it was being invoked to
manipulate a new worktree.
This reverts the remaining changes to checkout.c by 529fef2 (checkout:
support checking out into a new working directory, 2014-11-30).

Now that git-worktree handles all functionality (--force, --detach,

"git reset --hard" in place of "git checkout".

Now that git-worktree sets HEAD explicitly to its final value via either
git-symbolic-ref or git-update-ref, rather than relying upon
git-checkout to do so, the "hack" for pacifying is_git_directory() with
a temporary HEAD, though still necessary, can be simplified.
Since the real HEAD is now populated with its proper final value, the
value of the temporary HEAD truly no longer matters, and any value which
looks like an object ID is good enough to satisfy is_git_directory().
Therefore, just set the temporary HEAD to a literal value rather than
going through the effort of resolving the current branch's HEAD.

git-worktree currently conflates setting of HEAD in the new worktree and
initial worktree population into a single git-checkout invocation which
requires git-checkout to have special knowledge that it is operating on
a newly created worktree. The eventual goal is to rid git-checkout of
that overly-intimate knowledge.
Once these operations are separate, git-worktree will no longer be able
to delegate to git-branch the setting of the new worktree's HEAD to the
desired branch (or commit, if detached). Therefore, make git-worktree
itself responsible for setting up HEAD as either a symbolic reference,
if associated with a branch, or detached, if not.

Therefore, imbue git-worktree with the intelligence to determine a
branch name or detached state locally, and to perform error checking on
its own.

The caller of add_worktree() provides it with a command to invoke to
populate the new worktree. This was a useful abstraction during the
conversion of "git checkout --to" functionality to "git worktree add"
since git-checkout and git-worktree constructed the population command
differently. However, now that "git checkout --to" has been retired, and
add_worktree() has access to the options given to "worktree add", this
extra indirection is no longer useful and makes the code a bit
convoluted.
Moreover, the eventual goal is for git-worktree to make setting of HEAD
and worktree population distinct operations, whereas they are currently
conflated into a single git-checkout invocation. As such, add_worktree()
will eventually invoke other commands in addition to the worktree
population command, so it will be doing command construction itself
anyhow.
Therefore, relocate construction of the worktree population command from
add() to add_worktree().

Take advantage of 'struct child_process.env' to make it obvious that
environment variables set by add_worktree() are intended specifically
for sub-commands it invokes to operate in the new worktree.
We assign a local 'struct argv_array' to child_process.env, rather than
utilizing the child_process.env_array 'struct argv_array', because
future patches will make add_worktree() invoke additional sub-commands,
and it's simpler to populate the environment array just once, whereas
child_process.env_array gets cleared after each invocation, thus would
require re-population for each sub-command.

git-worktree currently conflates branch creation, setting of HEAD in the
new worktree, and worktree population into a single sub-invocation of
git-checkout, which requires git-checkout to be specially aware that it
is operating in a newly-created worktree. The goal is to free
git-checkout of that special knowledge, and to do so, git-worktree will
eventually perform those operations separately. Thus, as a first step,
rather than piggybacking on git-checkout's -b/-B ability to create a new
branch at checkout time, make git-worktree responsible for branch
creation itself.

When git-worktree creates a new worktree, it reports:
Enter "<path>" (identifier <tag>)
which misleadingly implies that it is setting <path> as the working
directory (as if "cd <path>" had been invoked), whereas it's actually
preparing the new worktree by creating its administrative files, setting
HEAD, and populating it. Make this more clear by instead saying:
Preparing "<path>" (identifier <tag>)

When check_linked_checkout() discovers that the branch is already
checked out elsewhere, it emits the diagnostic:
'blorp' is already checked out at '/some/path/.git'

dropping ".git" from the message.

The plan is to publish die_if_checked_out() so that callers other than
git-checkout can take advantage of it, however, those callers won't have
access to git-checkout's "struct branch_info". Therefore, change it to
accept the full name of the branch as a simple string instead.
While here, also give the argument a more meaningful name ("branch"
instead of "new").

die_if_checked_out() is intended to check if the branch about to be
checked out is already checked out either in the main worktree or in a
linked worktree. However, if .git/worktrees directory does not exist,
then it never bothers checking the main worktree, even though the
specified branch might indeed be checked out there, which is fragile
behavior.
This hasn't been a problem in practice since the current implementation
of "git worktree add" (and, earlier, "git checkout --to") always creates
.git/worktrees before die_if_checked_out() is called by the child "git
checkout" invocation which populates the new worktree.
However, git-worktree will eventually want to call die_if_checked_out()
itself rather than only doing so indirectly as a side-effect of invoking
git-checkout, and reliance upon order of operations (creating
.git/worktrees before checking if a branch is already checked out) is
fragile. As a general function, callers should not be expected to abide
by this undocumented and unwarranted restriction. Therefore, make
die_if_checked_out() more robust by checking the main worktree whether
.git/worktrees exists or not.
While here, also move a comment explaining why die_if_checked_out()'s
helper parses HEAD manually. Such information resides more naturally
with the helper itself rather than at its first point of call.

check_linked_checkouts() doesn't just "check" linked checkouts for
"something"; specifically, it aborts the operation if the branch about
to be checked out is already checked out elsewhere. Therefore, rename it
to die_if_checked_out() to give a better indication of its function.
The more meaningful name will be particularly important when this
function is later published for use by other callers.

When trying to switch to a different branch, that happens to be

that overlap the difference between the branches) while defeating

In order to allow linked worktree creation via "git checkout --to" from

checking out into a new one, 2014-11-30) dropped git-checkout's

setup conditionally based upon presence or absence of the --to option.
Now that --to has been retired and git-checkout is no longer responsible
for linked worktree creation, the NEED_WORK_TREE requirement can be

prepare_linked_checkout() respects git-checkout's --quiet flag, however,
the plan is to relocate "git checkout --to" functionality to "git
worktree add", and git-worktree does not (yet) have a --quiet flag.
Consequently, make prepare_linked_checkout() unconditionally verbose to
ease eventual code movement to worktree.c.
(A --quiet flag can be added to git-worktree later if there is demand
for it.)

The only references to 'new' were folded out by the last two patches.

The plan is to relocate "git checkout --to" functionality to "git
worktree add", however, this check expects a 'struct branch_info' which
git-worktree won't have at hand. It will, however, have access to its
own command-line from which it can pick up the branch name. Therefore,
as a preparatory step, rather than having prepare_linked_checkout()
perform this check, make it the caller's responsibility.
