In a TCL .exp file you'd split the lines with a '\' continuation
character.  Wouldn't that be more natural?  Like:

 /* { dg-additional-options                                   \
       "-DSTACK_SIZE=[dg-effective-target-value stack_size]"  \
       { target { stack_size } } } */

Might be less magical and simpler to implement too.

Thanks,
