It still works for negative numbers. The range -20:-10 means accept
between -10 and -20 inclusive. -10:-20 means reject between -10 and -20.

The only reason negative don't work in check_snmp is I could not find
ant OIDs that had negative output, so I excluded that input during input
validation. Of course, it just doesn't make sense for check_procs.

While the -r idea is slightly less arcane, it is also less flexible -
the current approach allows you to invert warning but leave critcals
normal. So I can't say I'm instantly in love with the idea. But we can
keep it on the table for 1.4
