X-Mailer: activitymail 1.26, http://search.cpan.org/dist/activitymail/
Content-Type: text/plain; charset=utf-8
Message-ID: <e3fd337fad249615@fantadrom.bsd.lv>

Log Message:
-----------
Make <funcdef> more robust:
If the first child is text, use it for .Ft,
then use all remaining children for .Fo.

Make <funcprototype> more robust:
Use all children but the first <funcdef> for .Fa.
