When trying to autocomplete svn operations in path containing UTF8 file
names, the following error occurs:

$ svn svn: E000022: Can't convert string from native encoding to 'UTF-8':
svn: E000022: /path/to/working/copy/2.?\208?\160...

I suppose this is because of $(LC_ALL=C _call_program....) in _subversion
completion code.
