CSTR 54 has a list of the original ones.  :-)

It's like .de rather than just ignoring its content, e.g.

    $ nroff | grep .
    .nr x 1 10
    \n+x
    .ig gy
    \n+x
    .gy
    \n+x
    ^D
    11 31
    $

Ah, OK.  I think one common error is forgetting to have sufficient \ in
a macro definition.  (What do others think?)  Having \fB and \\fB appear
different inside a .de scope would help show that.  But I also see that
having the fB be recognised is useful too.

After a .ft with no arguments, it seems.
