  • Committer: Matthew Fuller
  • Date: 2009-08-18 08:10:44 UTC
  • mto: (4772.1.1 integration)
  • mto: This revision was merged to the branch mainline in revision 4773.
  • Revision ID: fullermd@over-yonder.net-20090818081044-2due6ius01c4pwjl
Fix up some doctests to handle things ending up as RevisionSpec_dwim's
instead of RS_revno, and ending up as _dwim's (which may error
eventually, but won't until we try to evaluate them) instead of
insta-errors.
