When we report an entire update as skipped we shouldn't just bump its
base revision as that might break the working copy state. (E.g. checksums
might be invalid for the new revision). I think this fixes some of
issue #4323, although the desired 1.8 behavior might be different.

* subversion/libsvn_wc/update_editor.c
  (open_root): Not just notify, but also record the skip of the
    update anchor.

* subversion/tests/cmdline/update_tests.py
  (bump_below_tree_conflict): New test.
  (test_list): Add bump_below_tree_conflict.
