This matches the style used in C, which is good for consistency:
a_really_long_function_name(
double_indent_after_first_newline(
single_indent_nested_newlines))
We were already doing this for multiline control-flow statements, simply
because I'm not sure how else you could indent this without making
things really confusing:
if a_really_long_function_name(
double_indent_after_first_newline(
single_indent_nested_newlines)):
do_the_thing()
This was the only real difference style-wise between the Python code and
C code, so now both should be following roughly the same style (80 cols,
double-indent multiline exprs, prefix multiline binary ops, etc).
