CVS commit: src/lib/libwrap

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre

Modified Files:
        src/lib/libwrap: expandm.c

Log Message:
Always return from expandm() with errno unaltered, so on the
off chance it failed, there's still the possibility that whatever
processes the result will be able to deal with the %m that would
(presumably) be left in the format string.

And as a frill, don't call strerror() until we know we are
going to use its result (still call it only once, no matter
how many %m's are in the format string).
