PATCH: make compadd create empty groups

[Sven Wischnowsky <wischnow@xxxxxxxxxxxxxxxxxxxxxxx>]

This ensures that compadd without matches but with a -[JV] at least
creates the group (and otherwise does nothing else). This allows us to 
easily ensure a certain ordering of groups by just creating them with
`compadd -J foo' at the beginning. In a patch to follow.

Bye
 Sven
