Improve formatting of conditional expressions.
Before we did not really systematically format those. Now, we format the
different cases as:
- 1 Line: a ? b : c;
- 2 Lines: short ? loooooooooong
: loooooooooong
- 2 Lines: loooooooooooooooong
? short : short
- 3 Lines: loooooooooooooooong
? loooooooooooooong
: loooooooooooooong
Not sure whether "?" and ":" should go on the new line, but it seems to
be the most consistent approach.
