[svn-r10620] Purpose:

    Bug fix

Description:
    Opening a dataset (or named datatype) with "." for the name and using a
group ID for the location ID was not returning an error value.

Solution:
    Check the type of the object before attempting to open it (internally,
using a group ID and "." for the name maps to the group object).

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Solaris 2.9 (shanti)
    Too minor to require h5committest
