[MERGE][1.14][355273] Fix OSX test failures

[Brian de Alwis]

Hi Vincent.  I tried your branch on MacOS X 10.5.6 and there are still  
a lot of failures to do with unicode stuff.  It seems that the files  
with unicode filenames aren't being added during the test:

64.682  Selecting files for commit with filter []
     INFO  missing Žluťoučký
     INFO  Committed revision 3.
     INFO  Žluťoučký is not versioned.

This seems to be related to my LANG setting.  Using the default  
LANG=en_CA.UTF-8, many tests fail due to the above.  If I change it to  
C, most tests pass with only 5 errors.  I'll add the failing test log  
to the original report.

Brian.
