Michael Legleux 0cdc24023f Ignore checking formatting if no formatted files are staged (#1469)
I'm constantly harassed to follow the rules when I'm not doing anything
relevant.

This is an attempt to ameliorate that rather than `--no-verify` or just
disabling hooks altogether. 🍄 ☁️

Somebody might want to confirm `basename` is included with macOS.
