bug#15240: 24.3; Shell completion error: comint-last-prompt-overlay

[Rodrigo Rodrigues <rrodrigues@poli.ufrj.br>]

Shell completion is broken. I'm getting the error:

completion--some: Symbol's value as variable is void: 
comint-last-prompt-overlay
Looking at comint.el I can't find "comint-last-prompt-overlay", but I see:

(defvar comint-last-prompt nil
"Markers pointing to the last prompt.
If non-nil, a cons cell containing markers. The car points to
the start, the cdr to the end of the last prompt recognized.")
So I suppose that "comint-last-prompt-overlay" is gone in favor of 
"comint-last-prompt".

I was using the snapshot packages of emacs:
GNU Emacs 24.3.50.1 (x86_64-pc-linux-gnu, GTK+ Version 3.6.4)
of 2013-08-22 on louvi, modified by Debian

Now I turned back to the stable 24.3 version, so the configuration
details auto bundled with this mail are not the same.
