[rancid] term width changes

[Lee]

Maybe this falls into the "don't do that category", but I've been
doing rancid-run interactively as well as from cron & getting ~3MB
emails because the line width changes when run interactively vs.
started from crontab. For example:

- !VLAN: Gi1/0/45,
Gi1/0/46, Gi1/0/47
- !VLAN: Gi1/0/48,
Gi1/0/49, Gi1/0/50
- !VLAN: Gi1/0/51
+ !VLAN: 1 default active Gi1/0/1,
Gi1/0/2, Gi1/0/9, Gi1/0/10, Gi1/0/11, Gi1/0/14, Gi1/0/15, Gi1/0/16
+ !VLAN: Gi1/0/17,
Gi1/0/18, Gi1/0/19, Gi1/0/20, Gi1/0/21, Gi1/0/22, Gi1/0/23, Gi1/0/24
+ !VLAN: Gi1/0/25,
Gi1/0/26, Gi1/0/27, Gi1/0/28, Gi1/0/29, Gi1/0/30, Gi1/0/31, Gi1/0/32

This fixes the problem for me:
