[rancid] Expect to match Fortigate View-only prompt

[Jeff Moorse]

I recently edited the fnlogin script per a forum posting to match the
Fortigate prompt: 'Fortigate-400 # '

Now when logging in as a view-only user the prompt is 'Fortigate-400 $ ' and
RANCID hangs until timeout..

The script matches "\[#\\$]" for a set prompt, which should match the $ as
far as I can tell, although it never executes desired commands.

Thoughts?

Thanks,
Jeff
