The 'writebackup' option is to catch cases where writing fails. It
means that Vim can restore the original file. There is no point in
additional work.
If a user switches off 'writebackup' he must be prepared for losing
work. Perhaps this is not sufficiently clear to the user?
Considering how very few times this problem occurs I don't think it is
justified to do any work on this. Except perhaps a better explanation
in the docs in some place.
