               (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 semantic (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.
