git as hard requirement and 3.1.0

With pytest-benchmark I could on a system without git use the --benchmark-skip option to run my tests. With 3.1.0 I get traceback below. Is it intentional that git must be available even if user just wants to run the regular tests?

Traceback (most recent call last):

Hmmm … actually you’re right (it allows failures if bin exists but fails). I’ll fix this.

Awesome, thanks, works great
