So the commit of r3, 'Make a text mod to A/B/E/alpha.moved in the
first WC' is failing. I can't replicate this on my Windows box (nor
does the djh-xp-vse2005 box show it, but I see similar failures on all
the non-Windows buildbots. So yeah, something is wrong with the test
or some more general part of the test suite. Could you post the
complete log for update_tests.py 52 along with the post-test verbose
status of the 'other' WC that the test creates? That might shed some
light on the problem.

I updated the test in r35322 so we expect an update which moves a
locally edited to file to result in a text conflict on the move
destination and a tree conflict on the move source. That is this what
you expect after r35303 right?

Ok, weirdness ahead:

Using trunk_at_35321 update_tests.py 52 still fails for me the same as it
ever did (i.e. the alpha.moved cannot be found error):

  Note: Obviously there is a problem printing this
  exit message to the log on Windows, but I can't
  see how that would be related to this test.
  I see it in other tests as well.

But if I put a break in update_tests.py 52 just prior to the last
update and then run that last update myself from the command line,
then there is no error, and everything looks correct:

I've checked the paths in my test setup scripts, thinking the test run
was using the wrong svn.exe, but everything looks correct. Completely
perplexed by this.
