not possible to both --disable-whitespace and enable intrinsic case formatting

[stigh]

An example can be this example file, for reference called test.f90:

PROGRAM TestModule

  implicit none

  call test()

contains

  subroutine test()

    INTEGER i

    DO i = 1, 2
      print *, i
    ENDDO
  end subroutine

end program TestModule

I expected python3 ./fprettify.py test.f90 --case 1 1 1 1 ----disable-whitespace to set all lower cased intrinsics, but it has no effect at all.

During debugging I found out that this formatting is done in format_single_fline(), and is only called when impose_whitespace is True (!= --disable-whitespace).

Doing the following code change will get my expectations fulfilled:

--- a/fprettify/__init__.py
+++ b/fprettify/__init__.py

Then this is the result of python3 ./fprettify.py test.f90 -d -s --disable-whitespace --case 1 1 1 1

The code change above is not a fix that can be committed, since it breaks many test cases.
