hdf5/test/tvlstr.c
Quincey Koziol e1792ebb22 [svn-r7842] Purpose: 
Bug fix

Description:
    Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data.  This also affected fill values
for variable-length datatypes.

Solution:
    Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.

    Patched up dumper to display NULL sequences/strings.

Platforms tested:
    FreeBSD 4.9 (sleipnir)
