shell-mode: point left in the wrong place after output

shell-mode: point left in the wrong place after output

[T. V. Raman]

This is using the latest CVS  snapshot.

It looks like point gets left at the front of the inserted
outputfrom frm a shell command, rther than at the end.

Test:

See output below:
echo foo
foo
After the above, point is left before the 'f' of foo, rather than
after the subsequent shell prompt.

I don't know what you mean by "CVS snapshot", but I'll assume you mean
that you recently updated your CVS check out.

I tried:

   emacs -Q
   M-x shell-mode RET
   echo foo RET

and it worked just fine, with point ending right after the prompt.
Can you provide a more precise recipe?

Stephane --
cvs snapshot == latest checkout.

I'm seeing the problem with emacspeak running; the fact that you
dont see it in a vanilla session suggests that the new mods to
comint.el where you use copy-marker may be triggering a bug on
the emacspeak side.

I advice comint-output-filter to process the output -- but at
first check I didn't spot any reason why it should be breaking.

It happens with `C-u M-! echo foo'.  But IIUC this is supposed to
happen: in shell-command the mark is set before the output and after the
output is inserted point returns to the mark.  I suppose this is to
facilitate editing the shell command output?

So the behavior I'm seeing in the shell-mode buffer is identical
to what you report. 
I've not chased down the cause yet.

The main change is that comint-output-filter does not use
insert-before-markers any more.  So if you use `save-excursion' around
it, point will now stay in front of the insertion.

[T. V. Raman]

thanks for the tip, I definitely think this is the problem.
