=autfilt=. Doing so a bit like adding =cat %H>%O= as another tool: it
will also ensure that the output is equivalent to the input.
Similarly, if the tools being tested implement complementation
algorithm, adding the =--language-complemented= will additionally
compare the outputs using this own complementation algorithm. Using
this option is more efficient than passing =autfilt --complement= as a
tool, since =autcross= can save on complementation by using the input
automaton.
