comint-process-echoes related bug

[ami]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Setting (or customizing) comint-process-echoes to t disables the echoing of
commands entered in comint mode (specifically, *shell*).  However
comint-send-input will act on this regardless of whether it's doing a
"normal" send or a "fake" one, such as is called from comint-send-eof or
comint-skip-input.  That means that if comint-process-echoes is set to
non-nil and one hits C-d, C-c C-c, C-c C-z, C-c C-\, etc, comint-send-input
just hangs waiting for the shell to echo back the fake input.  One fix is to
temporarily set comint-process-echoes to nil from all the sites that invoke
comint-send-input in this way (i.e., not actually expecting anything to be
sent to the process).
