[rancid] RANCID/clogin context-change FWSM/ASA

[Alan McKinnon]

The code that does it usually looks something like this in main() (it
can be different for each *rancid parser script):

        if (!defined($prompt)) {
            $prompt = ($_ =~ /^([^#>]+[#>])/)[0];
            $prompt =~ s/([][}{)(\\])/\\$1/g;
            print STDERR ("PROMPT MATCH: $prompt\n") if ($debug);
        }

This should do the right thing:

	$prompt = ($_ =~ /^([^#>]+[#>])\s*$/)[0];

That will skip the first two prompts in your output below and pick the
3rd, and correct, one. To work, the FSWM prompt must behave predictably
like this.
