I am sorry if I was wrong.

Here's my testcase:
$ dd bs=1M seek=1 count=0 of=f1
$ dd bs=1M seek=1 count=0 of=f2
$ du f?
0       f1
0       f2
$ rsync --inplace f1 f2
$ du f?
0       f1
1,1M    f2

Since files are identical, I expect nothing is written. But a sparse file
became filled so something goes wrong. Any idea what?
