/* back to the 0x9B char */

Just as an addendum - risk of '0x9B bug' depends mainly on terminal
capabilities - while 'dumb' terminals are mostly safe (maybe except DoS
attacks, destruction of display, etc) - smarter ones are vunerable to
things like parsing arbitrary strings as typed from keyboard, changing
terminal options, writing files and executing arbitrary code (see
'capabilities' section on termcap manpage, then termcap entry for your
terminal type). Most of them, if implemented, are available via 0x9B
control character.
