A correction to the "man" pages posted for nroff terminal driving tables:
ignore the part that reads

	.I Nroff
	assumes that boldface mode is reset automatically by the
	.I twnl
	string, because many letter-quality printers reset the boldface
	mode when they receive a carriage return;
	the
	.I twnl
	string should include whatever characters are necessary to
	reset the boldface mode.

This was a local hack required by a bit of braindamage in the NEC Spinwriter
and certain Diablo printers; whenever these printers receive a CR they reset
the auto-boldfacing and auto-underlining modes.  Unfortunately this confuses
the hell out of programs with a straightforward and sensible model of the
printers they talk to (like "nroff"); anybody know what prompted this bit of
silliness on NEC and Diablo's part?
