rsync() translates delete=True wrongly

[Colin Watson]

codetree.fileutils.rsync translates delete=True into rsync -d. But the -d option to rsync doesn't mean delete:

        -d, --dirs transfer directories without recursing

This function should use the --delete option instead in that case, which will require a bit of arrangement since that option doesn't have a short variant and so can't be combined with the other short options in a single parameter.
