Edebug fails to remove overlay arrow when started from buffer with local
overlay arrow, like *grep*

Steps to repeat:

    emacs -Q
    M-x grep RET GNU src/* RET                  (assuming Emacs was started
in the Emacs root)
    M-x next-error RET
    C-x C-f ../lisp/progmodes/compile.el RET
    C-s compilation-goto-locus ( C-a
    C-u C-M-x
    C-x b *grep* RET
    M-x next-error RET
    q

Now, the Edebug overlay arrow is still present in the "compile.el" buffer,
even though Edebug no longer is active.

Sincerely,
    Anders Lindgren

FWIW, this is not a regression: I can see the same problem in 
Emacs 23.

I just installed a patch which should fix this, thank you,
