In this case, (and most cases, really) the TERM variable should just be
left as is.  It is set to "cygwin" when you are running from the console
and it should be set to "xterm" when you're running from an xterm.

On VMS, CTRL-H means "go to beginning of line".  So, undoubtedly xterm
is interpreting the [<-] key as a backspace.  I'm sure that google would
be able to help in redefining this key to something else (like DEL).

This isn't really a cygwin problem.
