Subject: mdocml: By popular demand, bring man.cgi default mode closer to what 
X-Mailer: activitymail 1.26, http://search.cpan.org/dist/activitymail/
Content-Type: text/plain; charset=utf-8

Log Message:
-----------
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.
