Re: Mark handling (Was: Changes to emacs/lisp/progmodes/grep.el)

    This then might be linked to another irritating thing I recently
    noticed: when double-clicking, the marked word is shown in region
    face, but reverts to normal face immediately.  The next double
    click sets region face semi permanently (till doing something
    else).  The next double click again only blinks region face, and
    so on.

That is definitely a bug; I think I can debug it from this.
Thanks.
