Unfortunately, those files are part of the *roff source distribution, so
you'd have to have a source license to get them.

V7 doesn't require them either.  (There seems to be a common assumption that
there's BSD UNIX and there's USG UNIX.  Many forget that there was a V7 UNIX
which actually ran on PDP-11s and preceded both BSD and USG UNIX.)

Also note:

1) under V7 and 4.xBSD, "bset" and "breset" are the bits to turn on and off
in the "sg_flags" field;

2) the remark about boldface mode being reset automatically by the "twnl"
string is *not* generically true; it was a local modification made here due
to the braindamage of the Spinwriter printers we have - a carriage return
turns off boldfacing on those printers,

and 3) the V7/4.xBSD "nroff" does not have the "iton" or "itoff" sequences
for turning on and off "italic" mode.
