Hm, this seems to be a deliberate change by upstream:

From Changes:

  - Required and optional arguments can now be put in a POD head section =head2,
    =head3 and =head4 for more flexibility

And from the code:

+    my $HEAD_START = qr{ ^=head[1-4]            }xms;
...
-    while ($man =~ m/^=head1 ($OPTIONS)  (.*?) $EOHEAD /gxms) {
+    while ($man =~ m/$HEAD_START ($OPTIONS)  (.*?) $HEAD_END /gxms) {


But I'm not sure if the side-effect that hits mpd-dynamic is also
done on purpose :)


Cheers,
