[svn-r6649] Purpose:
Bug fix. Description: Corrected fencepost error which was incorrectly checking for merging metadata at the front of the metadata accumulator. This now allows the metadata cache to cache I/O operations more efficiently. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ Linux 2.4 (burrwhite) w/FORTRAN Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/parallel & FORTRAN (h5committest not run due to my ongoing difficulties with C++ on burrwhite).
