Before SVN 1.8, if a file doesn't exist in the repository at the PREV revision and -r PREV is given, the PREV revision should be used -- not "revision 0". In SVN 1.8.x, it should actually be "revision 0". And in SVN 1.9.x, it should be "nonexistent".
Since you can't use -r PREV on a file that doesn't exist in PREV until SVN 1.7, this really only affects 1.7.x.
