The code should not save show vlan output if the switch is not doing VTP
transparent, which is why I was asking if VTP was being used.

another option, for rancid 3.0, is just comment-out the show vlan command.

yet another option, for formatting, is to break-up each port member into an
individual line.  less compact, but more easily read diffs
