I miss you here.  Emacs now by default also extends the region to the
right window edge.  OTOH both Mozilla and Thunderbird here extend the
region to EOL only.

With Firefox these diffs are boxed in a subarea of the Firefox window.
They do not start or extend at the window edges and text in these
boxes is static, can neither overflow into a newline nor be broken.

But I think that our (e)diff blocks are affected by the change and all
their face settings probably have to change, as well as tables and
listings.
