I knew someone would have replied something like this, sooner or later;
this is why I sent two patches instead of just one.
The first one is a bugfix, the second one is the implementation of a
feature that some are not really missing.

Anyway, I am not burning so much cpu power: I have implemented a very
simple flag mechanism to scan the screen only when blinking text is
added to the screen or if we are scrolling.
The screen buffer is not so big, but if you are so concerned about
performances, I can implement a more efficient way to know whether we
need to scan the screen or not...
