Indeed, this is something I believe should be addressed in the next
major version of Nagios-plugins. Most plugins out there tries to be
smart. I believe it doesn't always help users, and often makes
programming more tricky.

Plugins should eventually behave exactly and only as --help say and barf
if anything is unexpected. In the above case I guess the "unrecognized"
argument ended up being interpreted as a space-separated list of paths.
God knows what happened then when -p got hit but looks like it stopped
processing further arguments.

If I find some time I'll look into that and the free space warp around
reported earlier.
