Yes, known problem, Bob broke some spects of man.cgi when trying to
work around a bug in man(1) which i fixed in the meantime.
Somehow, it seems Bob never found the time to remove the bad
workaround and just use the repaired man program instead.
Right now, he definitely won't find any time; hopefully he will
around the time of the hackathon, and hopefully i will be there
to remind him.
Look at
http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/man/man.c:
the most recent commit fixes the bug the bad workaround is supposed
to address.
Yours,
Ingo
