Let find complete with directories after -path option

[inconstante]

The argument to find's -path option is supposed to restrict the search results to items that belong to the specified directory, so let bash-completion suggest directories to it.

Maybe that would be more inline with what other completions currently do, for instance, suggestion of perl modules after perl -M<TAB>.

On the other hand, I feel like that is re-implementing find itself. I do not feel like working on it, so I'll probably close this pull request.

Thanks for the feedback, Ville.

If you don't mind, I'd appreciate leaving it open even though you may not be working on it yourself, I or someone will pick it up eventually and the issue won't be forgotten.

I don't think improving this is a matter of re-implementing find at all. Just examine the arguments given to see what is the starting-point arg, and filter all dir completions that don't start with it. Defaulting to the starting point would probably be just a matter of ${cur:=$starting_point}, grepping := gives some ideas.
