[svn-r8567]

Purpose:
    H5Gget_comment bugfix

Description:
    H5Gget_comment:  Changed "Description" text and "Parameters"
    descriptions to indicate the following:
        'loc_id' can be file, group, dataset, or named datatype.
        'name' can be '.' if 'loc_id' fully describes the object.
        'name' is ignored if 'loc_id' is a dataset or nemed datatype.
    Also corrected the fact that the 'name' parameter description
        referred to setting the comment rather than retriving it.
