indent-region: unexpected result (Fortran2003)

[zimoun]

Dear,

>From the standard example [1], the function `f90-indent-subprogram'
(C-M-q) returns this unexpected output:

--8<---------------cut here---------------start------------->8---
Indenting module points...
END function does not match module.
Indenting module points...done
--8<---------------cut here---------------end--------------->8---


My guess is that it comes from the internal parser -- the entry point
is the function `f90-indent-region' -- which does not support the
Fortran 2003 norm; from my understanding.


Moreover, this snippet:

--8<---------------cut here---------------start------------->8---
submodule (singleton) sons
contains

 module procedure print_son
   print *,"son print ",this%child_num,count
 end procedure

 end submodule sons
--8<---------------cut here---------------end--------------->8---

is transformed, when applying C-M-q, into:

--8<---------------cut here---------------start------------->8---
submodule (singleton) sons
contains

  module procedure print_son
  print *,"son_ print ",this%child_num,count
end submodule sons

end submodule sons
--8<---------------cut here---------------end--------------->8---


The block detection is wrong. Is it a "feature" or a real bug?


Thank you in advance for any comments.

All the best,
simon
