* How to recognise end of stream?
* In the best case, the underlying input stream (in) ends just after the last EOF record
* Usually however, the stream is padded with an arbitrary byte count. Excel and most apps
* reliably use zeros for padding and if this were always the case, this code could just
* skip all the (zero sized) records with sid==0. However, bug 46987 shows a file with
* non-zero padding that is read OK by Excel (Excel also fixes the padding).
*
* So to properly detect the workbook end of stream, this code has to identify the last
* EOF record. This is not so easy because the worbook bof+eof pair do not bracket the
* whole stream. The worksheets follow the workbook, but it is not easy to tell how many
* sheet sub-streams should be present. Hence we are looking for an EOF record that is not
* immediately followed by a BOF record. One extra complication is that bof+eof sub-
* streams can be nested within worksheet streams and it's not clear in these cases what
* record might follow any EOF record. So we also need to keep track of the bof/eof
* nesting level.
