[rancid] hlogin irritated echo of window size on HP's " ESC[__; __R"

[Per-Olof Olsson]

Hello

Think I solved the irritating echo of window size by not try to redefine to full prompt 
sting in interactive mode for hlogin.

It's hard to find prompt sting on new HP's if not using hpuifilter. They almost don't use 
any <CR> or <LF>, just cursor control via ESC/CSI codes.

Also prompt sting is not used after redefine it, so why try to redefine it in interactive 
mode at all?!

Tested to not redefine prompt string in interactive mode on old 2.3.8, 3.6.2 and alpha 
from 20170519. All work nice with no echo of window size.

!!!!This patch is from ALPHA version!!!!

If you not try to redefine prompt string in clogin, it will also work nicely for 
interactive login to HP's!
