If you want to. But a simple a-b test (or is that an a_b test?) of
hyphens and underscores would be sufficient.

For anecdotal evidence, I prefer to write git branch names with
hyphens, eg "git checkout rosuav/process-check-run". It's not about
the typing (tab completion means I don't have to type either form),
it's about the way it looks. So there definitely is _some_ advantage
here. I just don't think it's significant, not worth the hassle of
changing things around. And this is still ASCII-only.
