No, not at the moment. It may be possible to have "$e=mc^2" in limegreen,
though (using lookahead assertions). This could be enabled by implementing
the "highlight only the first captured group" idea I mentioned earlier.

My approach was just to consistently highlight "$$e=mc^2$$", i.e. highlight
the complete expression, not just the inner "$e=mc^2$" (in fact, my latest
regexp would also highlight the complete expression "$$$$$e=mc^2$$$$$",
though this probably is nothing you'd actually write ;)).
