The lists in asciidoc may also start with '-' and I tend to use it
instead of asterisk because it's easier to see inside the C style
comments.

This is fancy way of doing !self->string.val[0]

I'm not sure if we should add the asciidoc validation into the metadata
parser. It feels like this could have been done easier in a perl script,
especially if we are going to add more checks.
