strange EDT keypad behavior

strange EDT keypad behavior

[John J. Dougherty]

Hi

I've been running EDT emulation on emacs 20.7 for some time, and it 
works great.

We recently upgraded a machine to emacs 21.2, and I've noticed 
something strange.

on 20.7, in EDT emulation:
  ESC 2 0 KP0 causes the cursor to drop 20 lines, as expected.

on 21.2, in EDT emulation:
  ESC 2 0 KP0 results in a minibuffer display "ESC 2 0 kp-0-" and 
emacs does nothing, apparently waiting for more keystrokes.

Note that ESC 2 0 KP, and ESC 2 0 KP- work fine on both versions of emacs.
ESC n <down>, ESC n e, etc. all work fine as well. Seems to be KP0 - 
KP9 that don't play well with ESC n.

A workaround is ESC n C-u KP0, but that is a definite step backwards.

I dug through the edt.el but couldn't spot why this is happening. A 
web search produced nothing useful.

Is there a way to revert this behavior back to that of 20.7?

thanks
jjd

It seems clear that Emacs thinks it is processing a prefix character.
Can you take a look at the keymaps that are being used
and try to see why?

What happens if you type just KP0?  Does that also wait for
more input?

I don't know how to use EDT emulation; I cannot construct
a way to test this myself.  Can you send a precise self-contained
test case, and explain what the commands do?
Please read the Bugs section in the Emacs manual, which provides
guidelines on how to write a bug report to give us the
necessary information so we can fix the bug.
