[rancid] terminal width on Cisco ASA

[Per-Olof Olsson]

Not running any ASA but IOS and nexus switches.

Have done some tests to extend width to max, by set width
it multiple times in clogin script.

Just now running clogin using width 500 (nexus max 512) or
"no wrap" for IOS switches supporting "terminal width 0".

If you not set width in scripts you will get
80 when running from cron ("default vt100") or
current window width from where you run command by hand.

In later versions of clogin width set to 80

Diff from my running version of clogin.in (rancid 2.3.6)
