Very nice, thanks! Maybe remame multiline_macro.c.out to multiline_macro.json
to get json syntax in editors? (multiline_macro.c.out.json would be ugly).

I also wanted to have perl parser which would take expected output from tests
sources put as comment, but I haven't finished Christian's effort. Thus atm it's
really better just to put files with output.

Kind regards,
Petr
