Re: [PATCHv2] grep documentation: clarify what files match

Mark Lodato [off-list ref] writes:

Clarify that git-grep(1) searches only tracked files, and that each
<path> is a glob, as in git-add(1).  Add an example to show a simple use
case for searching all .c and .h files.

The meta-variable <path> should be changed to an official term for
a path glob, and the description for this should be in git(1), not
git-add(1).  However, we don't yet have such an official term, so just
use <path> and reference git-add(1) for now.

Looks much better, even though I personally prefer a shorter "work tree"
and also think the official name of the stuff is "pathspec".

Will queue until an alternative materializes (if ever) ;-).

Thanks.
