  (forced_switch_failures): Wrap some text over 80 chars.  For the final
  update of the test, update the whole WC, rather than targeting a subtree.
  This avoids a spurious failure on Serf, which earlier in the test fails
  on a switch attempt (which this test expects to happen and is correct).
  The problem was that when using Serf, the switch added some addition files
  that neon (and ra_local and ra_serf) don't, before the error occurs.  The
  test was written in such a way as to expect the non-Serf WC state.  By
  updating the whole WC we avoid this assumption.
