'diff_tests.py 29 31' test failures over ra_serf

'diff_tests.py 29 31' are both failing for me over ra_serf because the
paths don't have their output listed in the expected order. Here's an
example from the test 29 failure, with "iota" listed before "A" (both
paths are at the root of the Greek tree):

--- snip ---
EXPECTED STDOUT:

Property changes on: A
___________________________________________________________________
Name: dirprop
   + r2value

Property changes on: iota
___________________________________________________________________
Name: fileprop
   + r2value

ACTUAL STDOUT:

Property changes on: iota
___________________________________________________________________
Name: fileprop
   + r2value

Property changes on: A
___________________________________________________________________
Name: dirprop
   + r2value

EXCEPTION: SVNLineUnequal
