	hide-show-mode hides only ever other subroutine in Fortran-mode
Date: Wed, 25 Apr 2012 16:36:28 +0200

[Message part 1 (text/plain, inline)]

Use the following example source code:

module test_mod
  implicit none

contains

  subroutine a()
  end subroutine a

  subroutine b()
  end subroutine b

  subroutine c()
  end subroutine c

  subroutine d()
  end subroutine d

end module test_mod

enable hide-show-mode (hs-minor-mode) and execute command
hs-hide-level when cursor is outside of any subroutine. The result is that
only every other subroutine gets hidden.
This can be also reproduced with emacs 23.2.1 (debian-stable).

Thanks for the report. At first sight, it looks like f90-end-block-re
and f90-start-block-re should not be anchored to the start of the line.
Expect to see this fixed in Emacs 24.2.

I can reproduce this on current master.

Did you ever look into this?

Not really. I think my conclusion was that hideshow would need to be
extended to allow functions rather than just regexps.
