Here is another patch, using ̀set-temporary-overlay-map'.

It fixes the problem with the message disappearing.

It fixed another problem: the fact that in the current version,
INC is always 1 when using the command repeatedly, as we would
expect 

C-u 4 C-x C-+ +

to increase by INC = 4 then again by INC = 4 again -- right now
it increase by INC = 4 on the first hit, then INC = 1 on the 
second.  

It also changes the behavior regarding C-x C-0, which ends
the loop.

Let me know what you think,
