Identical IDs for div and h-tags

[Nudin]

Currently a heading like == foo == is converted to something like <div id="foo"><h2 id="foo">foo</h2></div> – this is invalid HTML, since id's must be unique.

Note corresponding code is in function process_tag_h() in html.vim.

TODO:

• [ ] understand for what the div is good for.

There are two ways to make a link to an anchor in Vimwiki: [file#anchor] and [file#header1#header2#anchor], where you provide the complete header hierarchy. Because of this, an anchor needs two id's. The div is just a dummy tag so that you can give two id's to one header.

Looks like this is only an issue if there isn't higher level header.

For example:

= Header 1 =

== foo ==

Renders:

<div id="Header 1-foo"><h2 id="foo" class="header"><a href="#Header 1-foo">foo</a></h2></div>

It seems like this is fairly harmless unless trying to use the id with javascript or something.

I just noticed this while looking at @chipsenkbeil's vimwiki-rs HTML generation, where it's duplicated.
