It is sometimes useful in wdired to be able to move files into
directories that don't yet exist, e.g. when one is reorganizing files
and directories. The attached patch (against git HEAD), based on
previous work by Joakim Verona (source:
http://www.emacswiki.org/emacs/WDired), makes wdired create parent
directories needed as necessary for the destination files, conditional
on the variable `wdired-create-parent-directories'.

What do others think of this feature?
