GRCM - GRAPHIC RENDITION COMBINATION MODE can be "REPLACING" or
"CUMULATIVE", which affects whether we need to respecify all attributes
at each SGR, or can accumulate them.  Looks like we can't rely on the value
of this, so we have to emit a single SGR for all changes, with a "0" reset
at the front, forcing it to be effectively replacing.
