This is generally a function of your terminal emulator or xterm and is a
carryover from old DEC terminal's stupid keyboard mappings.

The attached XTerm file put in $HOME/XTerm will get xterms to send ctrl-h
from the backspace key.  Other programs like putty typically have a
keyboard configuration that permits setting the backspace key to send
either ctrl-H or a DEL character.

I leave it as an exercise for the student to figure out my other tweaks in
this file :-).
