I think this is exactly the function I'm looking for. I'm a little
uncomfortable relying on the fact that typical implementations don't
modify the string when there's no trailing slash, though.

I think I'm going to end up refactoring out the strip_path_suffix
function into a has_path_suffix and use that. That will avoid the
allocation and it doesn't rely on the generosity of OS implementers.
