bug#22025: Emacs 25 corrupts Emacs 24 .emacs.desktop.

[Alan Mackenzie <acm@muc.de>]

Hello, Eli.

(Recap of thread: the current emacs-25 branch desktop.el silently
converts a .emacs.desktop file into version 208, which is incompatible
with the desktop.el in Emacs 24.5.  I wrote an amendment, by which such
a conversion would happen only at the explicit request of the user.
That patch was the topic of this thread back in early December.)

I asked Juanma back then to review it, but he seems to have disappeared.
I hope nothing bad has happened to him.

I do think it would be a good thing for this patch to make it into the
first pre-test version of Emacs 25.1, to save our pretesters from having
their .emacs.desktop's becoming incompatible with their main Emacs
systems.

Could somebody else perhaps take on the role of reviewing my patch?
