True, but it will save some on support effort on nagios-help and
nagios-users where newbies generally ask why their plugins' output
doesn't show up in the gui while it does when they run it from the
command-line. A cut 'n paste of the run generally excludes any empty
lines so it takes several mailings to get it right.

stderr output is probably mostly useful in the gui only. I wouldn't want
to get notified about UNKNOWN states that only has debug output in them
(unless the stderr output is the *only* output). When I'm trying new
plugins and stuff I'm constantly monitoring the GUI anyways, and I guess
that's how the majority of home-cookers do it once past the alpha stage
of command-line runs.
The "(no output returned from plugin)" shouldn't appear if there is
output on stderr.
