Nice, but why add the "if" when it's doing nothing?
It's short-circuiting in the conditional.
I think René meant this:
/* just for side effects */
skip_prefix(name, "refs/heads/", &name) ||
skip_prefix(name, "refs/tags/", &name) ||
skip_prefix(name, "refs/remotes/", &name);
return name;
which still short-sircuits, even though I do think it looks
strange; "correct but strange".
Yes. At least to me it looks less strange than the same lines wrapped
in "if ... /* nothing */".
