[svn-r4560] Purpose:
Bug fix. Description: H5S_select_hyperslab fails to correctly define a hyperslab when the space to put the hyperslab into is currently a 'none' selection and the hyperslab operation is the 'or' operation. Solution: Detect the situation and internally modify the hyperslab operation to be a 'set' operation, since that's the next affect desired. Platforms tested: FreeBSD 4.4. (hawkwind)
