Changes since 5.5.2:
* Fixed lots of bugs regarding autofixing variable assignments in
continuation lines.
* Fixed checking of MESSAGE files, which also get fixed now.
* In variable assignments, commented assignments are aligned too.
* Fixed a crash when checking an empty patch file.
* The :Q modifier is only checked on predefined variables, to prevent
the --autofix mode from removing :Q from user-defined variables.
* Fixed lots of bugs in PLIST autofixing: relevant lines had been
removed, and the sorting was not correct.
