[rancid] CentOS 6.6, recent upgrade, now all CatOS devices broken

[Brooks Bridges]

Yeah, there's definitely some pretty significant changes in how the 
prompt is being handled.

 From 3.1-3.el6.x86_64:
     # match cisco config mode prompts too, such as router(config-if)#,
     # but catalyst does not change in this fashion.
     regsub -all {^(.{1,11}).*([#>])$} $prompt 
{\1([^#>\r\n]+)?[#>](\\([^)\\r\\n]+\\))?} reprompt
     } else {
     set reprompt $prompt
     }

 From 3.2-1.el6.x86_64:
     # match cisco config mode prompts too, such as router(config-if)#,
     # but catalyst does not change in this fashion.
     regsub -lineanchor -- {^(.{1,11}).*([#>])$} $prompt {\1} reprompt
     regsub -all -- {[\\]$} $reprompt {} reprompt
     append reprompt {([^#>\r\n]+)?[#>](\\([^)\\r\\n]+\\))?}
     } else {
     set reprompt $prompt
     }

Now we're into "Hell if I know regex well enough to figure that out" 
territory.  Anyone care to take a crack at it?  I'm more than happy to 
be the guinea pig.

>>         After many hours of digging, I've determined that the issue appears to be that clogin is not properly recognizing the end of the output of the commands.  Debug log is attached showing this behavior when running "show version", where it gets to the end of the output from the command and then just hangs there.  It appears that none of the regexes are being matched when the command prompt pops back up after the command completes (perhaps it's only looking for a 'more' prompt?).

My lack of perl, tcl, and expect skills are quite an obstacle here as well.
