svn commit: r319856 - head/bin/ln/tests

[Ngie Cooper]

New Revision: 319856
URL: https://svnweb.freebsd.org/changeset/base/319856

Log:
  Add a testcase for `ln -sF`
  
  The testcase fails today, so mark it with atf_expect_fail: in
  particular, the target (B) isn't being unlinked and the documentation
  doesn't suggest special handling for directories. Thus, there's either
  a doc or an implementation bug in ln(1) that needs to be resolved.
