Issue created Feb 02, 2017 by Alexandre Duret-Lutz@adlOwner

remove_alternation fails to detect non-weak automata

Discovered while discussing with @tmichaud.

bug

The output is incorrect because the input is not weak and remove_alternation() is currently only expected to work on weak automata. An exception should be thrown, but somehow the non-weak detection code is flawed.
