[rancid] [PATCH] Handle "invalid command" / " ^" lines in WriteTerm too

[Michael Stefaniuc]

Hello,

the ACE and SANOS devices do not know the "more system:running-config" thus
^
% invalid command detected at '^' marker.

will show up in the saved config.

The ASAs do not know the command either but they return "Invalid input"
which rancid already detects. Nevertheless a stray
^
will be added to the saved config file.
The attached patch deals with both problems.

License: Whatever it takes to get it accepted to rancid.
