# Our column limit is more around 80 characters but we want to avoid
# this rule to be over-agressive. So for clang-format, let's use a
# higher limit. Then let's put some biggish penalties on breaking on
# assignment, or parentheses, or other similar cases. Actually with such
# limits, if clang-format really ends up re-formatting, there might be
# something better to do code-wise (i.e. we might be in an akwardly
# over-nested block case).
