Ok, after a little playing Ive found that if you extend the 1,14 regex length a bit this starts to happen:

Press the <tab> key at any time for completions.
* Pretend_Switch:1 > couldn't compile regular expression pattern: quantifier operand invalid
    while executing
"expect -nobrace -re {* Pretend_Switch:1 ([^#>\r\n]+)?[#>](\([^)\r\n]+\))?} {} -re {[
]+} { exp_continue }"
    invoked from within
"expect {
            -re $reprompt       {}
            -re "\[\n\r]+"      { exp_continue }
        }"
    (procedure "run_commands" line 23)
    invoked from within
"run_commands $prompt $command"
    ("foreach" body line 145)
    invoked from within
"foreach router [lrange $argv $i end] {
    set router [string tolower $router]
    send_user "$router\n"

    # Figure out the prompt.
    # autoenabl..."
    (file "./clogin" line 688)


I know its just a regex thing but identifying where it is is proving fairly tough.

cheers

Never argue with an idiot. They drag you down
