[folding] should not fold whitespace after function

[Tyriar]

Consider the Python script:

def a:
  pass



def b:
  pass

Currently all whitespace following the pass in a is collapsed with it:

This will make it the code harder to read in some cases as there is no space between the functions are the author intended, making a look more like part of b.

To implement this we need to know more about the underlying language. Does a definition end with the last non-whitespace line, or with a line of the same indent. The current implementation is tuned for the JavaScript case:

function alwaysNull() {
  return 0;

}

[Tyriar]

This is something that can wait until language-awareness comes about. The def ends on the last non-whitespace line that is of the same indent level (or lower):

def a:
  something


  something_else # a ends here


def b: # since there was a deintent here

def a:
  something


  def b:
    something_else # a ends here


def b: # since there was a deintent here

For both these cases I would expect:

def a: [...]


def b: # since there was a deintent here

[Tyriar]

As @inergy points out on #4968, adding a newline at the end of the folded section will immediately add the new line to the folded block.

Is there a fix in sight? This *The current folding behaviour is super annoying 😅
