[RP] [PATCH] avoid infinite loop after using redo

[Bernhard R. Link]

The attached patch fixes two problems together causing
an infinite loop when quiting ratpoison in some cases:

src/actions.c pop_frame_undo and pop_frame_redo do
not change the value of rp_num_frame_undos

and

src/main.c clean_up does try to free rp_num_frame_undos
undo steps, causing an infinite loop if there are not that
many left.
(Perhaps better than this patch would be to create something
 actiong like clear_frame_redo and being called from here).

Hochachtungsvoll,
        Bernhard R. Link
