#### Extension: `tex_math_dollars` ####
Anything between two `$` characters will be treated as TeX math. The
-opening `$` must have a character immediately to its right, while the
-closing `$` must have a character immediately to its left. Thus,
+opening `$` must have a non-space character immediately to its right,
+while the closing `$` must have a non-space character immediately to its
+left, and must not be followed immediately by a digit. Thus,
`$20,000 and $30,000` won't parse as math. If for some reason
you need to enclose text in literal `$` characters, backslash-escape
them and they won't be treated as math delimiters.
