This used to be 'test -z "$it" || eval "$it"'; doesn't it make a
difference?

What is the value expected to be in this variable?  Nobody seems to set it
in our codebase, so I cannot say "with the current code, this rewrite is
safe" or anything like that.

I think eval is a better route, as it gives the caller more flexibility
about what shell code to run. The only use is here:

  http://article.gmane.org/gmane.comp.version-control.git/186757

which does work either way.

This is probably not related to your patch, but

	GIT_TEST_CREDENTIAL_HELPER=cache sh t0303-*.sh

passes OK for me while

	make GIT_TEST_CREDENTIAL_HELPER=cache T=t0303-*.sh prove

seems to get stuck forever.

It's because t0303 is the generic "test any helper" script, and does not
know how to clean up the credential-cache daemon. So the daemon sticks
around, holding onto a file descriptor that causes prove to hang.
If you look at t0301 (which runs the same tests on credential-cache), we
kill the resulting daemon explicitly. t0303 could learn hooks to do
this, but I didn't bother, as I didn't need them for testing the
osxkeychain helper (which is the only thing I've used t0303 for, as
t0301 and t0302 cover the in-tree helpers). I figured that somebody
could add the hooks easily if and when they needed.
