[execnet-dev] RSync Issue

[Charles Solar]

I'll make up a small test case but just so I do not forgot I found
another bug dealing with symlinks.
I think that all relative symlinks are broken, or else I do not
understand how they could have worked before.
I saw it be having a structure like this rsync:

lib/
   libnet.so -> libnet.so.1.0.0
   libnet.so.1.0.0

What it created on the remote side was

lib/
  libnet.so -> /tmp/rsynctemp/libnet.so.1.0.0
  libnet.so.1.0.0

The link on the remote side did not include the lib subdir in the
link.  After looking at the code I fixed it up but I do not think they
should be working at all since the code atm only works if the symlink
is in the root dest directory.

Ill send in a patch for you to look at.
