Completely empty files are not considered problems.

A line feed ends a line, alone or behind a carriage return; a bare carriage return and a form feed are whitespace, as they are to PostCSS. The fix writes the break the linebreaks rule asks for, or else the one the file spells its lines with, and a line feed in a file written on a single line.

The break is written behind whatever the file ends on, so a free semicolon, whitespace and empty lines at the end stay where the author put them. The one thing that comes off is a run of spaces and tabs standing alone behind the last line break, which would otherwise become an empty line.

The fix option can automatically fix all of the problems reported by this rule.
