I would be interested to know which problematic cases motivated this 
work; I did not find trace of it in the source.

Hmm, no, it doesn't do anything.
fuzzy would help on naming problems; in the "dest is UDF" case (with 
the default, --no-inplace, mode: 'file' gets tranfered as 
'.file.XXXXXX', then renamed to 'file'):
- the name is correctly renderered
- but the timestamps are not (well, they are transfered, but then reset 
to 'now' by the FS during the final renaming)

Thus my patch to swap the timestamping with the renaming when it is 
detected that the FS has this flaw.
