Bug when using SSH on CatOS devices

I'm using RANCID 2.3.1 to get config from a bunch of Cisco 6500 running
CatOS 6.4.

Login is via SSH (on FreeBSD 5.3 w/ OpenSSH 3.8.1p1).

cat5rancid has the following code at around line 1062:

   TOP: while(<INPUT>) {
       if (/> \(enable\) ?exit$/) {

where $clean_run would be set to true if the prompt matches 'exit'.
However when using SSH the exit becomes:

   Switch> (enable)Connection to switch.foo.bar closed by remote host.
   Connection to switch.foo.bar closed.

compared to this using telnet:

   Switch> (enable)exit
   Connection closed by foreign host.

which will match and set $clean_run to true. Hence $clean_run will
remain false when using SSH, making cat5rancid fail.

A quick hack is to just do '$clean_run = 1' at the end of the while()
loop, but it doesn't fix it for real.

Any ideas?
