The latter would be nice (and maybe even could be the default, as the
stdout is usually just going to --verbose output anyway). But I don't
think it works, because the $() is a subshell, so we lose the side
effect of test_tick incrementing the timestamp counter.

I wasn't following this thread carefully, but your suggestion to just
do "A=$(git rev-parse HEAD)" seems quite readable to me.
