Undocumented INDEX field

I have been playing around a bit with BiffViewer, and I have noticed
something odd.

When Excel generates an INDEX record, it populates the fourth field (which
POI calls field_4_zero) with an index to the DEFCOLWIDTH record. The old
MSDN documentation says that this field is reserved and must be 0. POI
will always set the field to 0, even if the record has previous contents.
