>Description:
vim's pod.vim syntax highlighting file supports the old-style =head directives,
in that it only supports =head1 and =head2. However, recent developments in POD
translators also support =head{3,4}. 
>How-To-Repeat:
Open a POD file in vim, insert a =head{3,4} directive, notice the lack of
highlighting.
