things in a rather complex way.
(1) Move is optimized to move directories if a fileset
has been included completely, therefore FileSets need a
special treatment. This is also required to support
the failOnError semantice (skip filesets with broken
basedir but handle the remaining collections).
(2) We carry around a few protected methods that work
on basedirs and arrays of names. To optimize stuff, all
resources with the same basedir get collected in
separate lists and then each list is handled in one go.
