made my changes, so CTLR + SHFT + F should produce an acceptable output.

I am still undecided, how to handle the layout properties section, maybe we 
should introduce commas, to make it more readable

version 1: current version with spaces before and after =, the properties 
cannot be distingished so good
( color = dark_green fill = dark_blue )

version 2: version without spaces before and after =, might be to narrow
( color=dark_green fill=dark_blue )

version 1: current version with spaces before and after = and two spaces 
between properties, so the properties cant be distingished better, 
unfortunately I did not get the formatter to do that
( color = dark_green  fill = dark_blue )

When inserting a block expression for a text element, the expression should be 
rendered in one line. Usually these expressions should not necessarily be that 
complex.

fromText text ( ) { fromCardinality};

-> formatted:
fromText text ( ) {
    fromCardinality
};

The formatter has already been improved a lot. Can we close this one for now 
and reopen it when we have concrete issues of the formatter?

We can close it, I had not found a solution, how to do formatting dependent on 
the use context of the rule, but when you have already fix it, we can close it.
