Hi Kristaps,
Bob Beck definitely wanted this for man.cgi, so i have put it into
OpenBSD. I'd like to push it upstream, as well; i think the problem
occurs in general as soon as you want to serve manuals from multiple
operating systems or releases from the same server.
OK?
Ingo

I don't have a problem with the feature in general, but why -I?

We have -O for output options (i.e. options bound to specific output
formats and used while generating the output), so by analogy,
this is -I for an input option (i.e. an option bound to the specific
input format, mdoc(7), and used while parsing the input file).
Yours,
Ingo
