Subject: [PATCH] John Wilson      2010-08-17 17:09:16 PDT

The are no event handlers for the middle mouse button, right mouse buttons, and
mouse wheel in the latest HG revision 4636. It has been like this for 3 months.
I made a patch for this, though I'm not sure if the Xbutton or mouse wheel code
is "correct" by your standards.
