Initialisation in declaration should require explicit save

[ZedThree]

Initialisation in declarations gets an implicit save, meaning the initialisation is not done on subsequent entry into the routine.

Bad:

subroutine foo()
  integer :: bar = 1
end subroutine

Good:

subroutine foo()
  integer, save :: bar = 1
end subroutine

Also good:

subroutine foo()
  integer :: bar
  bar = 1
end subroutine

Glad you've raised this, because I wasn't aware of this behaviour. Might have to go back to edit some old code I wrote...
