  Added a test case for bug #18359.
  This was another manifestation of the problems fixed in the
  patch for bug 16674.
  Wrong calculation of length of the search prefix in the pattern
  string led here to a wrong result set for a query in 4.1. 
  The bug could be demonstrated for any multi-byte character set.
