Fixes Homebrew/homebrew#31926.

If you do `brew install blah` it currently doesn't search for it. This
seems to be unintentional looking at this code as the exception thrown
by ARGV.formulae.each is not caught and handled. Instead, let's handle
this case and provide a little more usability around our taps.

See 5cd6b35 and 8eefd4e.

We haven't actually had any complaints about this in awhile; it appears
that cmake no longer picks up this specific framework.

Refs Homebrew/homebrew#11030.

If formulae names are passed as arguments check if just they are outdated. Additionally, return a failed code if they are outdated.

This will hopefully be able to stop people complaining about the outdated error code as they can now just run e.g.:
`brew outdated git && brew upgrade git`

Right now this code only produces false positives. When we have real
support for renames, we can implement it more carefully.
