[svn-r4508] Purpose:

Browse Source 
Document bug fix.
Description:
    When reading or writing to chunked datasets and the data needed datatype
    conversion, and the amount of data was more than one conversion buffer,
    data in the conversion buffer was getting corrupted.
Solution:
    Corrected error in advancing buffer pointer where it was being advanced
    by the number of elements instead of the number of bytes.
Platforms tested:
    FreeBSD 4.4 (hawkwind)
