I think we are miscommunicating here.  The problem in this case happens
when transient-mark-mode is NOT active.

Before installing a fix, I'd like to understand why a fix is needed.
AFAIR nothing has changed in this respect in term.el from emacs-22.
In emacs-22 transient-mark-mode was off by default, and the problem in
this report did not happen.

Has something changed in the way the transient mark is handled even when
transient-mark-mode is inactive?
