Summary: ESC and BEL allowed in nroff

The ADDENDUM to the NROFF/TROFF User's Manual that was released as part of
the UNIX System III product states: the "Escape and BEL characters are valid
characters in nroff and are accepted and passed to the output of the formatter.
Troff continues to absorb these characters."  This change was made to nroff
to support those users that wanted (any) access to special printer features
not directly supported by the nroff/troff language.  Use of ESC is
clearly not portable across (some) printers, and across (some) versions of
nroff.
