opener: force copy on 'a'ppend if nlinks() returns 0 (issue1922)

If pywin32 is not installed, 'os.lstat(pathname).st_nlink' is used for
nlinks(), which is always zero for all files on Windows.

To make sure we break up hardlinks if pywin32 is missing, we force
nlink = 2 if nlinks() returns < 1.

(this completely fixes issue1922)

N.B. bzr 1.13 has a bug that breaks this test.  If you see this
test fail, check your bzr version.  Upgrading to bzr 1.13.1
should fix it.
