If the EOF is reached (means no block found or really reached the last block),

Introduced rewineUpdateSeekPosition() which needs to be called after
pre-allocation is done, else the seek position (pointer) shows to the end of

Only seek back to old position if the header has been flushed.

Signed-off-by: Roland Häder <roland@mxchange.org>

If you don't rewind + update + flush header, the current seek position shows to
the end of the file. This is not what you want with empty files as the seek
position must show to zero (only "virgin" files).

These methods may never be supported as initialization of file-based stacks does
