PATCH: better control for _cd

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

This makes _cd use the tags local-directories and path-directories to
decide if those in the cwd and/or those in $cdpath should be
completed.

I.e. you can put in your _sort_tags:

  *::cd:*)
      comptry local-directories
      comptry path-directories
      ;;

to first complete only the directories in $PWD and the ones in $cdpath 
only if that fails.

Bye
 Sven
