Please put cover letter material like this after the "---" divider, or
include a "-- >8 --" scissors line before your commit. Either helps "git
am" realize which content should go into the commit message.

Please omit these lines, as they are redundant with your email header.

This one is useful, but it would be even better if it were the subject
of your email. :)

You would want to use the stable, scriptable "--porcelain" output, so
the completion is not broken by future changes to the "--short" format.
However, I do not think using "git status" is the best option. It
computes three things:
1. The diff between HEAD and index.
2. The diff between index and working tree.
3. The list of untracked files.
But you only care about (2) and (3), so you are wasting time computing
(1). I think the list you want could be generated with:
git diff-files --name-only
git ls-files --exclude-standard -o
and then you do not need to worry about grep or sed at all.

I think you'd want to use __gitcomp_nl to handle filenames with spaces.
Speaking of which, the output of status (or of the commands I mentioned)
may have quoting applied to pathnames. I think that is not something we
handle very well right now in the completion, so it may not be worth
worrying about for this particular patch.
Other than those comments, I think the intent of your patch makes a lot
of sense.

bash completion of "addable" files for `git add`
hi,
i've always been annoyed by having to type — or copy & paste — paths when i
wanted to simply add some files to the index. i know about the `add -i`
interface, and that improves things a little, but having bash completion for so
many other things it still seemed to much hassle.
so here's a patch adding bash completion on `git add` for modified, updated and
untracked files. i've also set up a pull request — before i found
`Documentation/SubmittingPatches`. fwiw, it's at
https://github.com/git/git/pull/29
best regards,
andi

Subject: [PATCH] add bash completion for "addable" files
this adds support for completing only modified, updated and untracked
files on `git add`, since almost always these are what you want to add
to the index.
the list of possible completions is determined using `git status` and
filtered using `egrep` and `sed`.
