Actually no, custom element tag names must be closed -- the issue is that
within custom elements, other tags are not indented when they ought to be:
<x-custom-element>
<div>Inner</div>
<x-custom-empty-element></x-custom-empty-element>
</x-custom-element>
FWIW, I'm going to start using html5.vim
<https://github.com/othree/html5.vim> as it adds support for syntax
highlighting as well as omnicompletion and indentation for custom elements.
But I think something in between my patch and html5.vim should be applied
to the vim tree.
(also, html5.vim implements indenting by simply adding '\|\w\+\(-\w\+\)\+'
to the tag list rather than adding a separate function to check for
hyphenated elements. I tried this but couldn't get it to work for some
reason.)
