diff-no-index: DWIM "diff D F" into "diff D/F F"
"git diff --no-index" was supposed to be a poor-man's approach to
allow using Git diff goodies outside of a Git repository, without
having to patch mainstream diff implementations.
Unlike a POSIX diff that treats "diff D F" (or "diff F D") as a
request to compare D/F and F (or F and D/F) when D is a directory
and F is a file, however, we did not accept such a command line and
instead barfed with "file/directory conflict".
Imitate what POSIX diff does and append the basename of the file
after the name of the directory before comparing.
