I think it's not that simple. The reason is, there is no need for a
leading "program" statement in Fortran. If there is any non-comment
line at the "top-level" (outside of a function, subroutine, etc) at
the start of the file, f90 mode assumes it is dealing with a program
without an explicit start.
Consider the following two cases:
1)
!! Program without an explicit PROGRAM statement.
!! Everything from the start of the file is implicitly inside the program.
include "stuff.f90"
write (*,*) 'hi'
end program
2)
!! Program with an explicit program statement.
!! This comment is outside the program
program foo
!! This comment is inside the program.
include "stuff.f90"
write (*,*) 'hi'
end program foo
The present behaviour is designed to make these two cases indent in
the same way. The behaviour is not specific to "include"; any
non-comment code will make F90 mode think this is a program.
I don't see any simple way to distinguish between your example and
case 1 above. So I think the behaviour of f90-mode is unlikely to
change in this regard.
