Correctly fix issue #2580 on Win32: Don't kill the tunnel agent.
Correctly fix issue #2580 on Win32: Don't kill the tunnel agent.

* subversion/libsvn_ra_svn/client.c
  (make_tunnel): On Win32, APR translates APR_KILL_ONLY_ONCE to
   APR_KILL_ALWAYS, terminating the tunnel agent prematurely and
   breaking the SSH and SVN protocol shutdown sequences.
   It is actually not necessary to kill the tunnel agent on Windows,
   since it will reliably die on its own once svn closes the pipe.
