reset after binary data

[Andrei Paskevich]

Could save myself an hour of nitpicking, had I looked into CVS first :)
Sorry, Marc! 

I have a question, though. By setting rvideo_mode to false at reset,
you cancel the change to rvideo_mode caused by 'ESC [ ? t'. Probably,
this is intended. But then, the reverse video won't be actually 
switched off until scr_rvideo_mode is called again. This can be 
provoked by BEL in videoBell mode, or by another 'ESC [ ? t', but, 
I suppose, if we want to drop reverse video on reset, we must do it
by calling scr_rvideo_mode(false) from scr_reset() (which, BTW,
will by itself set rvideo_mode to false).

Best regards,
Andrei
