Comment (by catalyst):

 `tor.1.txt` documents the port number as optional for ExitPolicy, so if
 it's a tor bug, it's a documented one.  It doesn't explicitly say whether
 the `0x` prefix is allowed for specifying hexadecimal port numbers.  A
 comment in `exit_policy.py` says that the `exitpattern` spec in `dir-
 spec.txt` is stricter than what torrc allows.  Is the problem that tor is
 propagating some `exitpattern`s to descriptors or to the control protocol
 without normalizing them to the stricter `dir-spec.txt` grammar?
