Sorry but it will not work to use rancid for unpriv level, and ">"-prompt.

After some try to grab all open information in unpriv mode from cisco 
switches, there have to be some changes to fix a working script.

I add a new switch type/script where I replase all "return(-1)" abort on 
"authorization failed" to "retrun(1)" continue on "authorization 
failed". See included diff for rancid to rancid_noen

Add -noenabler to clogin command to not have to change in my running 
.cloginrc settings

To run cisco rancid script in unpriv mode, there must be some code 
update to find >-prompt and to match commands (cmds_regexp) with 
 >-prompt. Today rancid script only match for #-prompt.

Notice that "show running-config" in nopriv gives error text
  "% Invalid input detected at '^' marker."
and you have to set "found_end" before exit "write terminal" parsing
else you will not get a clean run.

If I don't have access to "show running" there is left one
extra line "more system:running-config" in output.
Can't understand to remove that extra line from my rancid_noen just now.

If I run my rancid_noen vs. rancid using full priv there is no diffs in 
outputs to switch files.
