Hmm.

	$ git grep -e 'test "\$' | wc -l
	712
	$ git grep -e 'test ".\$' | wc -l
	183

We are very inconsistent about such usage, generally, and of course
POSIX is very clear about the 'z' not being needed in a three-argument
"test" used for string comparison.  Is there any platform that is
usable for git (e.g., that implements "$( ... )") and has that
problem?
