Another candidate, close to the place of the previous example:
(tmp_win->w is the actual client window)

The do_not_propagate_mask now includes PointerMotionMask where it
doesn't in twm.

This also makes no difference. Which makes me wonder why it's needed.

The PointerMotionMask has been there for a long time: since bzr revision
11, i.e. ctwm-3.2p1. This was still by Claude Lecommandeur. It was
checked in into the monotone repository on 2003-02-02. Too bad there are
no detailed change logs from the changes back then...
