Subject: By popular demand, bring man.cgi default mode closer to what man(1) does:
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=46723f19eb8576452765d24b71ce746695447690;p=openbsd

By popular demand, bring man.cgi default mode closer to what man(1) does:
Even when there are multiple pages with the same name in different
sections, show one of them, using the same priorities as in the
default man.conf(5) file.
