[patch] Underscore in hostnames

[Fabio Olive Leite <fleite@redhat.com>]

Hi all,

Even though underscores are not really valid in hostnames, many people
use them and they seem to be tolerated in many places. So I propose
the one-liner below to see what you think.

This one-liner adds underscore as a valid hostname character for NFS
mounts.
