By convention, context patterns are of the form «:foo:…» where «foo»
identifies a particular library / module / plugin for namespacing
reasons.  So, it says ":urlglobber" and not something else because
that's what the author of urlglobber named urlglobber.

The zstyle completion actually does this; try completing
«zstyle :vcs_info:<TAB>» or «zstyle :completion:<TAB>».

In this case the best approach is to look for the style name.  In other
formats of the manual, each style name has its own index entry.

Potentially some of the above should be added to the manual.
