Wow 10 years.
Maybe one reason this has not been implemented is there are other options. 
For example I have been using a shell script as a wrapper to reduce the
iteration of this bug, here is how it works:
1) Create 2 lists of files; destination and source with the files sizes and
path
2) For each file that is in the destination but not the source
3) Create a subset of the source list containing file of the same size
4) If the subset > 0 hash the destination file and each file in the source
subset until a match is found
5) Ensure the dir exists on the destination and move/rename the file.
6) On some systems hash can be as expensive as re-transferring the file so I
added an option to move the file if there was one match (only sometimes
hashing), and another to skip if more(never hashing).

Though as I am re-evaluating my backup strategy I am looking into git-annex and
other solutions.
