Well, you didn't get my meaning. I should put it more clearly.

I mean, if it's not legal to set `help-char' to nil, then when I press 
C-x C-h,
it would show me a buffer with a list of key bindings starting with C-x.
But I want it invokes C-x DEL. So the workaround I'm looking for is
how to keep `help-char' to C-h and avoid showing me the help buffer when 
I press C-h.
(Note I can't find another good char to replace C-h. Also note f1 is not 
a legal character)

On the other hand, if it's legal to set `help-char' to nil, the problem 
has gone.

Because this setting breaks term mode. I am wondering it's a bug in term 
mode or I shouldn't do so.
Thank you anyway.
