At one point it was documented. Then later, we pulled the documentation,
since the interface is less than ideal (it doesn't handle trailing
newlines, although those are rare); a better interface would start
searching for shells that support the POSIX feature of ${var%/*}, so we
don't even have to fork to implement this on decent machines.
But yes, I agree that until we implement the better interface, we probably
ought to revive the documentation.
