Comment (by strk):

 -T does not remove the old directory, but simply refuses to consider
 it a target directory in which to _move_ things:

 {{{
   -T, --no-target-directory
       treat DEST as a normal file
 }}}

 If the directory exists, it would fail.

 But then we add --backup=t, which renames the target directory,
 if existing. Finding a name which is available, from a pattern.

 Anyway, simplified the code by forcing removal of target dir
 with r14737. Once happy this will need to be copied over
 the 2.2 branch.
