Suggestion: CD_SILENT option.

[Andrej Borsenkow <borsenkow.msk@xxxxxx>]

Hi!

Just small suggestion - add CD_SILENT option to make `cd' silently change
to non-local directory (using CDPATH).

Rationale: almost everybody includes some indication of current directory
in prompt. As in zsh it is much more easier/elegant to do it as in other
shells I know of, this printing of `cd' is just unneccessary. It just
wastes line on terminal.

I include diffs against zsh-3.0-pre3 just in case ;) (Sorry, cannot
include diffs to info/man - no idea how to do it).

greetings
