[svn-r8630] Purpose:

    Bug fix

Description:
    Correct potential file corruption from mis-setting the metadata accumulator
address. (Bugfix contributed by Sean Monner <seanm@quadrus.com>)

Solution:
    When the new metadata overlaps with the end of the metadata accumulator and
the accumulator grows in size, don't reset the address of the accumulator, since
it hasn't moved.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
    too minor to require h5committest
