Looks like you forgot to add `docs/scheme.scheme` to commit.
I see [["constant.language","#f"]](https://github.com/ajaxorg/ace/pull/1231/files#L2R121) in the test, but `#f` is highlighted as `["punctuation.definition.constant.character.scheme", "constant.character.scheme"]`.

I'd suggest to move constant.language into it's own regexp and change keyword regexp to something like `[a-zA-Z_$][^\s()[]{}"'+]*`
