Import new option -o include in modules file

[Matthew Herrmann]

Hi guys,

I've had an idea to resolve the cvs ls issue: introduce a new option -o
which adds a default entry to the modules file upon import:

import -o proj faredge start

Then, people could put that in their .cvsrc files and you could guarantee
that cvs co -c would give a true list of the repo's contents. Also a new
user doesn't have to learn about the admin files straight away (and possibly
shouldn't unless they're the cvs admin).

Comments welcome.
