Whitespace before/after double colons about fprettify HOT 3 CLOSED

For double colons, whitespace conventions are rather subjective (e.g. manual vertical alignment). Therefore I did not want to impose any strict rules for whitespaces around double colons.

Thank you for the prompt answer.
Yes, I agree that this is subjective, but in future it would be very nice if one can select some convention, for example,

   integer :: x
   double precision :: y

or

   integer          :: x
   double precision :: y

by giving an option.

Yes this would be a useful feature. I'm still hesitating because vertical alignment requires some heuristics based on adjacent lines, while the initial decision was that whitespace formatting should not be context aware (i.e. formatting is applied on each line independently).
