Subject: - Scott Barrett provided a test case for a segfault in the FTP code
 and the   fix for it. It occured when you did a FTP transfer using  
 CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but 
  switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being  
 cleared properly.  Scott's test case is now known as test 539 and it  
 verifies the fix.
