Bug ID: 12036
Summary: Multiple --link-dest, --copy-dest, or --compare-dest

reproduction
We have observed what seems like incorrect behavior when using a command like
this:
rsync -avc --link-dest=../copy_dest/good --link-dest=../copy_dest/bad src/
dest
with a directory stucture that looks like this:
.
├── copy_dest
│ ├── bad
│ │ └── file # contains different content from src, but same
attributes (e.g. mtime)
│ └── good
│ └── file # contains same content as src, but different
attributes (e.g. mtime)
└── src
└── file
Using the command above, we see that "bad/file" is hard-linked into "dest",
even though it is different from "file" in src.
I've attached repro.sh which reliably reproduces this for me on the latest
version of rsync.
