  • mto: This revision was merged to the branch mainline in revision 2363.
  • Revision ID: john@arbash-meinel.com-20070315223535-d3d4964oe1hc8zhg
Add an overzealous test, for Unicode support of _iter_changes.
For both knowns and unknowns.
And include a basic, if suboptimal, fix.
I would rather defer the decoding until we've determined that we are going to return the tuple.
There is still something broken with added files, but I'll get to that.
