In this case it's a real bug that breaks the working copy.

          svn rm wc/A/B/f
          svn cp wc/g wc/A/B/f
          svn rm --force wc/A # doesn't update text-base
          svn revert -R wc/A
          echo 123 >> wc/A/B/f
          svn ci wc # fails with checksum error

Yes, a lot of it gets easier when properties are in the db and
pristines are just a checksum. But mark_tree_deleted will still need
to update the properties and the checksum, and at present it doesn't
do it.
