This happened during the "great file task unification period" between
1.1 and 1.2.  At the same time when <deltree>, <copydir> and
<copyfile> got deprecated.  <copy> and <move> gained a whole bunch of
new abilities and I don't think anybody really noticed that <move>
became a lot slower than <rename> because nobody tried to move larger
directory trees.

<rename> only works for a single use-case: I want to move a whole
directory tree to a new name, there doesn't exist a directory of that
name already and the directory lives on the same file system as the
one I want to move (cross filesystem moves on Unix or moving between
drives on Windows is impossible with File#renameTo).

<move> is so much more flexible - and if you set the filesets up the
"correct" way it isn't that much slower.
