Odd "backspace" behavior (SOLVED)

[Dan Mahoney, System Admin]

All,

I had an issue a few months ago, I previously had the issue described 
here...

http://www.mail-archive.com/address@hidden/msg02218.html

I traced it a bit more, and the multiple-of-8 issue (which I somehow 
recall being an issue on other systems) didn't seem to be the case.

What I eventually traced it down to was that I got very very odd behavior 
when doing funny shell things, specifically when running commands with 
%signs in them, and what it would seem was happening was those % signs 
were getting interpolated.

for example, the long command...

ls | grep "^qf" | xargs grep -c theirusername | cut -d : -f 1 | cut -c 
3-20 | xargs -I % rm -v df% qf% | more

..really screwed up both cursor positioning and my prompt, and would do 
the same thing when I up-arrowed to it in my history.

So, my previous tcsh prompt was:

set prompt="%{\ek%}tcsh [$HOST] %{\e\\%}\%"

Once I switched over to

set prompt="%{\ektsch [$HOST]\e\\%}"\%

(that is, fit the entire prompt within a single escape-sequence bracket, 
even though the tcsh [$HOST] part are normal characters)

Everything started behaving.

Many thinks to Trent Buck for the direction.  It got me most of the way 
there.
