      contains: fix the semantics · 23722c03

      * spot/twaalgos/contains.cc, spot/twaalgos/contains.hh: Fix the
      code and documentation.

      tl: add some implication-based rewritings for "<->", "->", and "xor" · 4ce0d928
      Alexandre Duret-Lutz authored
      This prevents an exception from being raised if NNF is not performed
      on Boolean properties and implication-based checks are used.
      
      * NEWS: Mention the issue.
      * spot/tl/simplify.cc, doc/tl/tl.tex: Add some rules.
      * tests/python/ltlsimple.py: Test them.
