The check out of project containing checked in symlinks creates a workspace
with files instead of symlinks. E.g., creating a repository containing
the elements:

$ svn co file://$PWD/test/trunk/data
A data/file.link
A data/file.txt
Checked out revision 3.
$ ls -l data
total 12
lrwxrwxrwx 1 mrohan mrohan 8 Jun 28 17:55 file.link -> file.txt
rw-rw-r- 1 mrohan mrohan 16 Jun 28 17:55 file.txt

Within Hudson, the workspace contains the elements:

$ ls -l data
total 16
rw-rw-r- 1 hudson hudson 13 Jun 28 17:53 file.link
rw-rw-r- 1 hudson hudson 16 Jun 28 17:53 file.txt
$ cat data/file.link
link file.txt

There is no newline in the file created.
