While we do not recommend the idiom ".Fl Fl long" for long options

because it is an abuse of semantic macros for device-specific
presentational effects, this idiom is so widespread that it makes
sense to convert it to the recommended ".Fl \-long" during the
validation phase.  For example, this improves HTML formatting
in pages where authors have used the dubious .Fl Fl.

Feature suggested by Steffen Nurpmeso <steffen at sdaoden dot eu>
on freebsd-hackers.
