Re: [groff] anyone seen ".ny0" ?

Hi Walter,

Given .ny0 seems to be limited to the libx11 man pages here so
https://www.x.org/wiki/ might be a starting point to tracing its
addition in their source tree.

It seems to always be just before the .TH that should start a man page,
but sometimes there's a «'\" e» or similar between the two, indicating
eqn(1) is required as described in man(7).  That magic comment only
works as the first line of the file though, so it looks like these man
pages have had a `portability' header added at their start, and that
ends in .ny0?

> I could not find this in the groff manual. It seems to do nothing.

I was surprised

    $ groff -Ww <<<.ny0
    $ groff -Ww <<<.foo
    $ 

didn't complain about those unknown things as they could be typos that
it should help catch.
