Couple of directives: additional_packages, filter_packages, multilib_blacklist mention package_globs in its definition. Definition of these is slightly different per directive.

I'm interested in filter_packages and for my rpm foo-1.2-1.src.rpm the correct match is supposedly foo-*.src or foo.src depending on the backend. That's surprising as it isn't always shell glob of the rpm (with version).

Please improve package_glob definition in the documentation.
