kingst-la2016: separate complex calls from caller's control flow

Don't mix complex invocations with their evaluation of the return value
and change of flow in the source code. This is even more important for
indented multi-line argument lists and indented conditional branches
which follow. As a byproduct this reduces text line length and further
increases readability. Break other long lines. This commit picks low
hanging fruit, leaves more complex cases for another commit.
