Well, this has no real effect in comparison to the current code. The
only addition are the move from "file" to "file~" and then the deletion
of "file~". Both operations doesn't work on the content of the file.
Anyway, I don't like the "file~" stuff very much.

I'm not sure whether this is necessary. Wait a few days, I recently
written a "backupcopy" plugin which copies the current file to a given
directory after it was saved. So, this has basically the same effect as
the the left "file~" in case of an error. But instead of the (IMO) ugly
"~" extension, the extension can be configured, e.g. to contain a
timestamp.
I guess using the backupcopy plugin is probably enough to solve the
problem together with a dialog box reporting the problem to the user
(as Jeff suggested).
And as I told before, when the system of the user is running out of
disk space there are most probably bigger problems than the changes in
the current file in Geany.
