Right, the regexp wasn't anchored anywhere, so after a reindent or other
suddent change the highlighter might believe that it's in the middle of
a string...

I pushed a new version, anchoring at the beginning of the line.  This
means that multi-line strings ending with a dollar sign will still be
broken, but no more broken than before, e.g.:

foo() ->
    "Multi-line string
ending with a $".

bar() ->
    this_gets_highlighted_as_a_string.

git fetch git://github.com/legoscia/otp.git dollar_font_lock
