Re: html checkbox to markdown

[John MacFarlane <fiddlosopher-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

The proper way to do this is:

 % echo '<p><input type="checkbox" /></p>' | pandoc -f html+raw_html -t markdown
`<input type="checkbox">`{=html}`</input>`{=html}

Using the `raw_html` extension with the html reader will cause the unknown things to be included as raw HTML rather than dropped.  If you don't want the pandoc 'raw attribute' syntax, you can disable that:

% echo '<p><input type="checkbox" /></p>' | pandoc -f html+raw_html -w markdown-raw_attribute
<input type="checkbox"></input>

So if you want to read HTML without erasing stuff, you are generally better off specifying the *Markdown* reader. The results can be kinda ugly, but there's no way around it: there is no 'native' Markdown for a checkbox input, so it uses the fallback.
