strange error code with 3.1

[Carlos Carvalho]

Got this with
rsync --list-only --files-from=list directory dummy > output 2> errors
to get a local file list:

...
rsync: link_stat "file-name" failed: No such file or directory (2)
rsync: link_stat "file-name" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1141) [sender=3.1.0dev]
rsync: [sender] write error: Broken pipe (32)

Everything is normal except the last line. I don't understand the code
32 return value, I think it should be 23.

This happened with HEAD-20091127-0430GMT.
