I have finally used --same-file because I have discovered some 
interesting uses in addition to read/write testing:

'--same-file'
     Allow INFILE and OUTFILE to be the same file or device. This can
     be used to test the writing ability of a drive. It can also be used
     to copy part of a file to another location inside or beyond the
     end of the same file if '--input-position' and '--output-position'
     are different.

The only incompatibility I have found is with --truncate. I have also 
had to work around a "bad file descriptor" error with --preallocate.

I expect to release it tomorrow.


Best regards,
Antonio.
