As some of you may already know, I keep an untracked directory
called "Meta" at the top-level of the working tree of the Git
source tree. This "Meta" directory is actually a single-branch
clone of the git.kernel.org/pub/scm/git/git.git that checks out
its "todo" branch, where files like whats-cooking.txt lives.
So, what I often would do is
$ git -C Meta add whats-cooking.txt
after updating the draft of the next issue of the "What's cooking"
report. The command line completion support for "git add" knows how
to complete this when I stopped typing the above after whats-" and
hit <TAB>. It seems that __git_find_repo_path helper function that
notices "-C there" and discovers the $GIT_DIR, and _git_add helper
uses __git_complete_index_file that honors the discovered $GIT_DIR
to find paths in the correct index, which is wonderful.
But the same does not work for the step before I can decide to
actually "add" the contents, which is to "diff", i.e.
$ git -C Meta diff whats-<TAB>
does not complete.
Anybody wants to take a crack at it?
Thanks.
