--- Comment #3 from Manuel López-Ibáñez <lopezibanez at gmail dot com> ---
Perhaps Fortran FE formatters can call the standard formatters if an
unknown directive is found? I don't know how C/C++ handles this case (does
it support this %-directive or does it switch to the standard pretty
printer?) but there is no reason to not do the same and share the code if
possible.
