Good point. The same is true for -q, too. ->unmatch_name_only (-L) and ->status_only (-q) are already handled correctly because they are checked before binary_match_only. We can do the same for ->name_only.

As with the option -c/--count, git grep with the option -l/--name-only should work the same with binary files as with text files because there is no danger of messing up the terminal with control characters from the contents of matching files. GNU grep does the same.
Move the check for ->name_only before the one for binary_match_only, thus making the latter irrelevant for git grep -l. Also add a simple test for each of -l, -L and -q. The latter two options were already handled before binary_match_only, so no code changes were needed to make them pass.
