Re: [PATCH] Document that "git add" only adds non-ignored files.

Thanks for the reminder, but I wonder if it is good to update the description of this command, and ls-files to use the same wording for consistency. We seem to use <pathspec> to mean "this is not necessarily a filename -- we glob", so that may be a good candidate (we do not have <pathspec> in glossary yet -- we would need to add).

Please don't touch description for diff-* family -- right now, they say <path>, because they do not glob. If we decide that it is a good idea to glob (which I suspect we don't for the low-level stuff, but we probably do for the "git-diff" wrapper), we would update the code and the description at the same time.
