While you are touching the vicinity of the code, could we lose that "cut"
and replace it with "rev-parse --short HEAD", without the hardcoded 1-7?

I wondered if we can use a single "git describe" output for all the
describe/default and failure cases but didn't come up with a good way to
do so only by using bash built-ins.
