Before this commit, if `sparsefile` were a regular file of non-zero
size whose contents are all null bytes, then
dd if=sparsefile of=outfile conv=notrunc
would have resulted in `outfile` having zero size as reported by
`stat`. After this commit, `outfile` will have the same size as
`sparsefile` (even if the contents are represented sparsely by the
filesystem).
