[svn-r10238] Purpose:
Optimization
Description:
Speed up I/O on enumerated datatypes (including those nested in compound
datatypes, arrays, etc.) if the destination datatype is a proper superset of
the source datatype.
Solution:
Detect the situation and treat as no-op datatype conversion.
Platforms tested:
FreeBSD 4.11 (sleipnir)
Too minor to require h5committest
