# Ensure that we can dedupe the last block of a file whose size isn't

|
# - Create two 'a' files file whose size isn't block-aligned.
|
|
# - Create two 'b' files file whose size isn't block-aligned.
|
|
# - Dedupe the last block of file1 to the last block in file2 and file3.
|

# - Check that files 1-2 match, and that 3-4 match.
|
|
# - Check that the ends of 1-2 and 3-4 match, and that 1-3 don't match.
