Literal parser breaks with unmatched "<"

const regularLiteral = wikilinks ? makeRegexParser(/^[^{}[\]$<\\]/) : makeRegexParser(/^[^{}$<\\]/)

Because of "special character" < in regularLiteral (which was added in the more recent HTML parser), the following line breaks:
This is a sentence with < in it.

Removing < (from regularLiteral) seems like it fixes the issue, but I don't have the repo locally to do any of the other tests.
