That seems reasonable.  Did it work for you?

I did a little scrounging via Google and saw a message that referred
to something *very* similar - instead of <backspace> producing '^?',
it produced '^H'.  The suggested solution was:

stty erase ^H

I modifed that to fit my situation and tried:

stty erase ^?

This seems to have solved my problem because now 'less' properly
interprets <backspace>.  The post from which I (gratefully) stole this
information (http://www.cygwin.com/ml/cygwin/1999-07/msg00203.html)
ended with this caveat:

====>
This might have unexpected side effects in other programs, but at
least not in bash which puts the tty into raw mode (by way of
readline).
<====

Anybody know if I should expect untoward consequences by putting
'stty erase ^?' in my .bash_profile?

Thanks!
