[svn-r12501] This is a small bug fix.

h5ls uses -S flag to display datatype in a machine-readable form. Since
VMS is not a case sensitive system, triple quotes around S are needed; fixed.

h5ls -w80 -v -S tattr2.h5 

test still reports failure due to line 311 in the tattr2.ls file "Modified: XXXX..."
Document it for now in the command file.
