[Buildbot-devel] Patch to fix Buildbot copy mode issue with symlinks in Subversion on FreeBSD

[Pete Curry]

Hi,

Below is a patch that seems to fix a Buildbot copy mode issue on
FreeBSD with symlinks in a Subversion working tree, where files'
contents are copied instead of the symlinks, leaving files in the
Subversion ``~'' state. The patch explicitly sets the -R -P flags
which are defined in POSIX and should have the same behavior as GNU
cp -r across all POSIX OSes.

I have tested it on FreeBSD and GNU/Linux, but I do not have access
to other platforms.

Thanks,
- Pete Curry
