New feature for chmod (and I'm surprised nobody got around to it...)

[Brendan Byrd]

  -d, --filesonly         don't change the permissions of directories

Ever ran a "chmod -x *" command, but hate having to go back and re-chmod 
the directories?  Now you don't have to with a "chmod -d -X *" command.

This program has been out for how long?  I'm really surprised it's not 
in here by now.  There have been a number of occasions when I wanted 
something like this, so I finally broke down and hacked it in.  Enjoy!
