Improve standalone * and _ parsing.
The `NOT_STRONG_RE` regex matchs 1, 2, or 3 * or _ which are surrounded by
white space to prevent them from being parsed as tokens. However, the
surrounding white space should not be consumed by the regex, which is why
lookhead and lookbehind assertions are used. As `^` cannot be matched in a
lookbehind assertion, it is left outside the assertion, but as it is zero
length, that should not matter.
Tests added and/or updated to cover various edge cases. Fixes #1300.
