[rancid] Re: ignore certain diff's

[Ryan Speed]

just to follow-up for completeness.

Thanks Dave,

your suggestion worked with minor modification, I made the changes and
forgot about it (mainly because I stopped receiving the bogus emails).

I changed --ignore-matching-lines='^call-forward' to
--ignore-matching-lines='.*call-forward.*' which has filtered out the
call forwarding emails I was receiving.

Thanks again,
Ryan
