Yes, that is the definition of what partial mode does with a partially
transferred file.  The manual recommends the use of the --compare-dest
option to work around this, but that doesn't appear to do the manual
says at all, so it looks like there is either a bug in the handling of
--compare-dest when --partial is enabled, or a bug in the manual.

One thing that the manual doesn't say is what file should be preferred
if there is a matching file in both the compare-dest dir and the real-
dest dir.  This becomes important if we want to use --compare-dest as a
holding zone for partial files since we would need to have the code
prefer the compare-dest file over the real-dest file if we make it put
partially transferred files into the compare-dest dir.  The current code
prefers the real-dest file over the compare-dest file and puts partially
transferred files into the real-dest dir.

Opinions?
