Sorry this followup is so far behind the thread!  1000 unread articles
in comp.windows.x, I'm sure you all know the feeling.

I believe the reason for using substructure redirect as the test for
a window manager is that all window managers must (by definition!)
have selected for this.

This is not the case for the other masks mentioned; hence substructure
redirect is the right choice for window manager detection.

Sorry if this point is blindingly obvious, but I did not see it in any
of the discussion.
