Hi all,

I recently upgraded from RANCID 2.3.3 to 2.3.6.

I noticed a bunch of diffs generated on our Cisco ASA firewalls after
a recent collection.

Index: par-fw01
RCS file:
retrieving revision 1.17
retrieving revision 1.18

> !Serial Number: JMXXXXXXPQ!

Note the exclamation mark ("!") appended to the serial number string.
This does not appear in the command output when entered interactively.

There seem to be a few possible culprits mentioned in the CHANGES file
between 2.3.3 and 2.3.6.

Our ASAs are running software release 7.0(x).
