[PATCH] Improved "git add"

[PATCH] Improved "git add"

This fixes everybodys favourite complaint about "git add", namely that it
doesn't take directories.

We use "git-ls-files --others" to generate an arbitrary list of filenames,
and thus also automatically honor ignore-files while we're at it.

Side note: there's a lot of room for improvement here. In particular, if
we have a long list of filenames (importing a big archive), this will just
do a big stupid for-loop and add them one at a time. Maybe it should use

	generate-list | xargs -0 git-update-idex --add --

instead.

Also, I think we should have a default ignore list if we don't find a
.git/info/exclude file. Ignoring "*.o" and ".*" by default would probably
be the right thing to do.

But I think this is a good first step.

Use the "-n" flag to just show the list of files to be added without
adding them.
