If no selection is given, Format the Current Statement

[kashev]

Is it possible to format the statement the cursor is over if use_entire_file_if_no_selection is set to False?

It's tricky. Unless you give yapf enough context to properly determine the nesting depth it will probably either mangle your code or do nothing.

More generally -- yapf is intended for reformatting entire files not single statements.
