Hi Carlos,
not realy a good plan, but maybe it helps nevertheless.

ENDCOPY is a good canditate for rotating too.

w_current->page_current->selection2_head->next,
fix_x(w_current, w_current->start_x),
fix_y(w_current, w_current->start_y));
As the selection is still at (w_current->start_x, w_current->start_y) I
think its better to rotate around that point. The selection is still at
(start_x, start_y). The next mouse-motion event will put it back to the
mouse cursor.
Manipulating start_x, start_y may be an option, too. I have no idea how.
The rotate comand erases (the not exising) original buffer and redraws
it as selection at the screen. Thats the garbage. Let's delete it.
o_erase_selected(w_current);
But I think this will leed to problems when rotating in ENDCOPY state.
The ENDCOPY will cause additional headache. When rotating we're rotating
the original buffer too. =:-(

Sorry not a good one.
