4Allow $math$ markup in text and docstrings, ignoring \$.

6The $math$ markup should be separated from the surrounding text by spaces.  To
7embed markup within a word, place backslash-space before and after.  For
8convenience, the final $ can be followed by punctuation (period, comma or
9semicolon).
