Rsync to a Read Only file system

[smokin.jake at mac.com]

I think your product is awesome, but I am experiencing an unexpected  
behaviour.

$ rsync -avviPH /Users/alan/Desktop/rsync_test\ Folder/

rsync error: some files could not be transferred (code 23) at main.c 
(1058) [sender=3.0.0pre8]

The destination file system is  Read Only, but RSYNC takes the time  
and looks as if the transfer is happening, but of course it is not.
I would like RSYNC to terminate as soon as it knows its destination  
is Read only.

The transfer is from a  Mac OSX to Debian Linux HFSPlus file system.

OSX
  rsync  version 3.0.0pre8  protocol version 30.PR16
  Capabilities:
     64-bit files, 32-bit inums, 32-bit timestamps, 64-bit long ints,
     socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
     append, ACLs, xattrs, iconv, file-flags

Linux
rsync  version 3.0.0pre8  protocol version 30.PR16
Capabilities:
     64-bit files, 64-bit inums, 32-bit timestamps, 64-bit long ints,
     socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
