[svn-r3653] Purpose:
    Bug Fix
Description:
    Partial hyperslabs which exactly fit the size of the lowest dimension of
    a chunked dataset weren't being output correctly.
Solution:
    Forgot to divide the offset (seq_len) by the size of the lower dimension
    hyperslabs - fixed now.
Platforms tested:
    FreeBSD 4.2 (hawkwind)
