Treating 'not found' packages as errors

Hi,

I'm using yum for keeping all my machines properly installed. Unfortunately I
occasionally makes mistakes and asks yum to install packages that does not
exist, this gives printouts like (with enough verbosity enabled):

  No package misspelled_package_name available.

but the exit status from yum is unfortunately 0, so there is no way to find this
out from a script. I humbly suggest something like:
