Unintuitive --version when a package is given

Description

"pkg-config --version foo" should do one of the following:

1. Act like "pkg-config --modversion foo"

2. Produce an error message. Bonus points if the error message contains "--modversion" in it.

Current behavior (of ignoring the "foo" and producing the version of pkg-config) is incredibly non-intuitive.
