Previously, two underscore characters in a document would mark the entire
space between them as italic, no matter how far apart. Now we only accept a
single consecutive newline within an inline-formatted span, so hard-wrapped
documents will still format nicely but stray characters won't mess up your
entire document.
Note that the highlighter for backtick-enclosed spans was modified,
even though it's redundant with the code-block highlighting introduced
in 5bc62c694.
