Summary: The "-S" flag on the check_by_ssh plugin does not work

Initial Comment:
The "-S" flag on the check_by_ssh plugin does not work in versions 1.4.3 and 1.4.6, it does work when I run version 1.4.2.  Not sure what changed from one version to the next.  Suppressing stderr altogether for this plugin would also resolve the issue.

Up to the 1.4.2 release, "-S" skipped the specified number of lines
written to stderr.  With 1.4.3 and newer, "-S" skips the specified number
of lines written to stdout.  I now changed the behaviour as follows:

1) "-S" skips the specified number of lines written to stderr.
2) If the number specified via "-S" minus the number of lines written to
stderr is larger than 0, the difference is used as the number of lines
written to stdout to skip.

However, if you want to ignore all output written to stderr by ssh(1)
itself (such as logon banners), simply use the "-q" flag.

Mentioning "--skiplines" was an error in the "--help" output, the long
option of "-S" is called "--skip".  I fixed the "--help" output.

Thanks for your report, Holger

Also broken in 1.4.8

The '--skiplines n' option is broken as well, with -S the script will run
and fail on output, with --skiplines the script fails with:
"./check_by_ssh: unrecognized option `--skiplines'"

check_by_ssh from nagios-plugins 1.4.1 works correctly.
