I've noticed (with curses interface) that there are a lot of
update_status(BL_FLUSH) calls when nothing on the status lines
has changed. It happens while just wondering around, not due to
deliberate botlx update. This eliminates one of the causes.
Updating hero's experience points or score (via u.urexp) was
requesting a bottom lines refresh even if the relevant options to
see those changed values was off. The botl code would send a flush
directive even though nothing visible was modified. (I have a fix
for that too, but am holding back while hoping to find some of the
other causes of unnecessary botl requests.)
