fix for cvs ls

[Peter Bowen]

I sent out a patch to add ls functionality to cvs, but found a couple of
bugs with it.  It will seg fault if you use the -a switch, and it
doesn't work in client-server mode.  I have fixed these issues, and have
attached the patches.

Thanks to everyone who has provided feedback.  I still need some help
getting it to list directories, though.  

Thanks.
Peter
