show fortran function names in svn diff

问题

I've learned that if I place *.f90 diff=fortran in ~/.config/git/attributes, then git diff shows fortran subroutine/function names in the hunk headers.

Do you know how to achieve this for svn diff?

There is a svn option -x -p for C functions, but I haven't figured out a corresponding option for fortran.

Thanks
