In the mdoc(7) parser, inspect roff registers early such that all parts
of the parser can use the resulting cues. In particular, this allows
to use .nr nS to force SYNOPSIS-style .Nm indentation outside the
SYNOPSIS as needed by ifconfig(8).
To actually make this useable, .Pp must rewind .Nm, or the rest of the
section would end up indented. Implement a quick hack for now,
a generic solution can be designed later.
