This is to workaround differences in minidom's pretty-printing that
occurred between Python 3.7 and 3.8.

When dealternating the VWAA for GFa, our result had two states that
could not be fused by simulation because of unmatched acceptance mark.
With this change, the result can be simplified.

test case.
* NEWS: Mention it.
Fixes#327.

This mixes the subset construction (for 1-state rejecting SCCs) and
the breakpoint construction (for larger rejecting SCCs). The
algorithm should probably be rewritten in a cleaner and more efficient
way, but that should do for a first version. It should be easy to
extend it to support Büchi acceptance (since the breakpoint
construction works for this) when we need it.
