For _ports, we have an option for whether numbers or service names are
required/allowed. -n conflicts with the hidden style so is not the best
choice. I don't especially object to separate functions but it could
lead to uses of _alternatives for both _uids/_users where either are
allowed which would be fairly awful. Same for using _users || _uids. A
single function can handle that better.
