* sync with MontFerret/ferret * fix --param handling When params is converted to map it uses strings.Split, which slices a string into all substrings separated by :. * remove impossible conditions nil != nil * delete ineffectual assignments * replace '+= 1' with '++' * remove useless comparison with nil * merge variable declarations * remove bool comparison * fix imports * fix imports * delete unused file * use copy instead of loop * delete unused DummyInterface * remove unnecassary break statements * tidy modules
