[rancid] Re: rancid issues with IOS XR

This looks similar to a problem we had where the '#' symbols in our
banner were being mistaken for the '#' in the enable prompt and
confusing rancid.  One of my colleagues applied this patch before I
was involved in our rancid install:

423a428,435
>         -re ".+##########.+Verification"      {
>                                 # Account for the hosed up banner via telnet
>                                 exp_continue
>                               }
>         -re ".+##########.+"  {
>                                 # Account for the hosed up banner via ssh
>                                 exp_continue
>                               }

This may be a silly patch but it's worked for us and I've never had to
reevaluate it.  If you used something like this you might have to
change the number of contiguous hashes based on the output you sent.
