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.
