[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)
