The coding style clearly states:

	The preferred limit on the length of a single line is 80 columns.

	Statements longer than 80 columns should be broken into sensible chunks,
	unless exceeding 80 columns significantly increases readability and does
	not hide information.

Going beyond 80 chars may sometimes be warranted for code, but the
exception is not intended for comments.
