Ok, from your "this might work" it sounded like you hadn't. :-)

Which means it's broken, of course ;-) but wouldn't surprise me.

It can't?

'"([^"]*(\\")*)*"' should match quoted strings with '\"' as long as they 
don't also have '\\', and it should be possible to handle that also, 
just it makes the regexpr more complicated. But it would be much, much 
easier if SEPARATE_ARGS Did The Right Thing :-(.
