Bug#366004: bash completion for cdcd

[Martin Schulze]

Package: cdcd
Severity: wishlist

Hi,

attached please find a simple function for bash completion for the
cdcd command.  I'd be glad if it would be added to future versions.
License is GPLv2 or higher, same as for cdcd itself.

Regards,

        Joey
