Subject: If man(1) only has one single argument, always interpret it as a name,
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f92821066656139515728a69942c07e2e59482a5;p=openbsd

If man(1) only has one single argument, always interpret it as a name,
never as a section.  Who would have thought that people call their
manual pages 7z(1), 9c(1), 9p(1), and 9p(3)...
Patch from Sebastien Marie <semarie dash openbsd at latrappe dot fr>.
