This is a followup to issue #548, which was caused by edges being dropped. In that context dropping edge was not really desirable, so let's make this behavior configurable. * spot/parseaut/public.hh: Add a new option. * python/spot/__init__.py: Likewise. * spot/parseaut/parseaut.yy: Honor that option. * tests/python/parsetgba.py: Add a short test for it. * NEWS: Mention it.
