Keep params below the call

[sbcgua]

To #21

Here is my suggestion. :)
If not possible to recommend it this way then at least refer as a grounded alternative and let people choose their preferred way.

P.S. Sorry for long silence with this ...
P.P.S occasionally run a "remove trailing spaces" - will remove these changes if requested not to mix the changes ...

How is this different from the pattern the guide already mentions as an alternative in If you break, indent the parameters under the call with

DATA(sum) = add_two_numbers(
  value_1 = 5
  value_2 = 6 ).

However, this is the best pattern if you want to avoid the formatting to be broken by a name length change.

Adding an additional section for this seems redundant to me.

We discussed this in a decision meeting and came to the following conclusions:

1. The suggested formatting is sound.
2. Exactly that formatting is already described in subsequent sections of the guide.
3. The style of the examples are not in sync with the rest of the guide ("XXXXX" instead of real code).

Especially because of point 2 we think it does not make sense to merge this PR.
