*: make GNU licensing statement forms more regular
...
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

Subject: [PATCH] diff: correct handling of labels
This fixes an issue where diff would apply labels to files in the
inverse order, when using -L or --label.
This fixes it in order to be compatible with gnu diff.
It also makes it not an error to specify more than one label.
The behavior for such cases is that they override the label for the new
file.
