The formatter has always been inconsistent about how to refer to the limit that it tries to fit code in. The option name (which is older than when I started working on the formatter) is "--line-length". But the public API and all of the internal code uses "page width".
This renames that option to "--page-width". The old name is still supported (but hidden in help) for backwards compatibility.
In practice, this option isn't used often, so this likely won't affect many users. We've already made a major version bump, so now seems like a good time to clean things up as much as possible.
cc @johnmccutchan since the inconsistency was bugging you. :)
