Subject: Refactor format_indent_attributes implementation

Fix code style and revert redundant parameters/whitespace changes.

Also remove format_each_attribute_on_new_line - we're only introducing one
extra formatting flag. The flag implies format_indent but does not include its
bitmask.

Also add a few more tests.

Fixes #14.
