[rancid] Trailing exclamation mark on Cisco ASA serial numbers

[Dale Shaw]

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.

Example:

dale at box:.../firewalls/configs$ cvs diff -D '1 day ago' par-fw01
Index: par-fw01
===================================================================
RCS file:
/usr/local/rancid/var/CVS/firewalls/configs/par-fw01,v
retrieving revision 1.17
retrieving revision 1.18
diff -r1.17 -r1.18
8,9c8
< !Serial Number: JMXXXXXXPQ
< !
---
> !Serial Number: JMXXXXXXPQ!
dale at box:.../firewalls/configs$

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).

Cheers,
Dale
