The `mark-defun` function does not work as expected in
f90-mode. Test using the following file:
------- test.f90 ----------------------------------------------
subroutine a
end subroutine a
subroutine b
end subroutine b
subroutine c
end subroutine c
----------------------------------------------------------------
Note: subroutine a must be on line 1 of the text file. Place the cursor
inside subroutine a and execute `mark-defun`. The subroutine is
correctly marked. Now place the cursor inside subroutine b and execute
`mark-defun`. In this case subroutine b and subroutine c are both
marked instead of subroutine b only. Now add a new empty line above
subroutine a, place the cursor inside subroutine a and execute `mark-defun`.
In this case the whole buffer is marked instead of subroutine a only.
