cg-status and empty directories

Hello,

Short story: Recently I noticed a change in the way, cogito handles
empty directories.  Before, empty directories have been silently
ignored. Now cg-status always lists the status of empty directories as
unknown, but it still refuses to add them. If there is a good reason
for this behaviour, can someone enlighten me?

Long story: I'm using cogito to track and distribute changes on the
/etc directories of a few (almost) identical machines.  Whenever I
install a package which modifies somthing in /etc, I commit those
changes.  But with cg-status reporting all the empty directories as
"unknown", my brain needs a long time to parse the list and find the
really unknown files which shall be put under version control.

Many packages put empty directories under /etc, and although only a
few of those directories are actually needed, the automatic removal of
those packages will fail if I remove the empty directories manually.  
Equally, the removal will fail, if I put a .placeholder file into
those direrectories and cg-add it.  Is there a simple way out?

Regards,
Jim
