So clever it's stupid

So clever it's stupid

[Phil Carmody]

How do I turn off the utterly obnoxious behaviour of '<' in shell mode?
(Emacs v.21.4.1)

<<<
sh-maybe-here-document is an interactive compiled Lisp function in `sh-script'.
(sh-maybe-here-document ARG)

Insert self.  Without prefix, following unquoted `<' inserts here document.
The document is bounded by `sh-here-document-word'.
>>>

I give all my heredocs meaningful individual names, and certainly don't want 
emacs inanely thinking that I want all the terminators called 'EOF'.

It's so completely brain-dead that if I try to type a command like
  echo '<<< doing phase 2 >>>'
I don't get past the second chevron before it's shat unwanted garbage
in my file.

Similarly it doesn't seem to understand that people might want to use
both expanded and non-expanded heredocs, or sometimes want leading
tab removal, but at other times not want it. And as for herestrings,
they're right out.

Magic '<', for me, must die. How do I ensure I never ever see that
abomination again? (Unbind the key and make it self-insert in a 
bunch of relevant hooks? Or is there just a variable I can set to 
'off' somehow?)

The former:

(add-hook 'sh-mode-hook (lambda () (local-unset-key "<")))

Many thanks. It looks like all of the shell subtypes share the
same major mode. So once it's hit on the head for sh, it will
be gone in csh, etc., which is good.

Hi,

   It's so completely brain-dead that if I try to type a command like
     echo '<<< doing phase 2 >>>'

Here is a workaround so you can keep the "magic-<":

C-u 3 C-q < RET

I know, it is overkill if you type this hundreds of times.
Another way to have this could be to make "<" reacting
differently according to the situation maybe using a different
input method.
