grep.c: teach 'git grep --only-matching'
Teach 'git grep --only-matching', a new option to only print the matching part(s) of a line. For instance, a line containing the following (taken from (`man gitcvs-migration` or `git help cvs-migration` if git is Is printed as follows: $ git grep --line-number --column --only-matching -e git -- \ | grep ":27" The patch works mostly as one would expect, with the exception of a few considerations that are worth mentioning here. Like GNU grep, this patch ignores --only-matching when --invert (-v) is given. There is a sensible answer here, but parity with the behavior of other tools is preferred. Because a line might contain more than one match, there are special considerations pertaining to when to print line headers, newlines, and how to increment the match column offset. The line header and newlines are handled as a special case within the main loop to avoid polluting the surrounding code with conditionals that have large blocks.
