Subject: 24.5; f90-indent-subprogram indents incorrectly when the buffer
includes type, extend(...)
--text follows this line--

When indenting an entire f90 buffer that contains an extended type, the
indentation comes out incorrectly. Steps to reproduce:

1. Start Emacs with `emacs -Q'
2. Enter a program. A simple example:
program example

  type :: e1
     real :: a
  end type e1

  type, extends(e1) :: e2
     real :: b
  end type e2

end program
3. Automatically indent, either with C-M-q or C-x h C-M-\. The result
is:
program example

  type :: e1
     real :: a
  end type e1

  type, extends(e1) :: e2
  real :: b
end type e2

end program

f90-indent-subprogram should not have changed anything from the input in
this case. Indenting with tabs, manually, line-by-line, works correctly.
