Hi jens

I hadn't noticed the "skip over html" bit - having looked at it more
closely, it seems that the highlighting is done before macro resolution.
(I was wrong before - I made assumptions and didn't check them :-( )

I haven't really got time at the moment to look into this properly. but
maybe you could modify highlighttext so that it skips over macros and
their arguments?

I am away next week, if you haven't found a solution by the following
week, I could look at it then.

cheers,
Katherine
