Hi.

Locally, I have cleaned up pwd_mkdb(8) and added support for modifying or
adding records pertaining to a single user. This is based on code from PR
7366, but has been re-written to behave sanely. If no-one objects to it on
principle, I'll commit it in a couple of weeks (I'm away all next week).

Also, WRT to services_mkdb(8), why was this added and then removed? The log
messages suggest that the corresponding libc code was missing. (I am happy
to write it.)
