Resolves #581.
The implementation of the rule is fairly simple right now. It just goes through all elements of an alternative and tries to find the pattern
(?=a)bora(?<=b). So it won't attempt to do clever things like assertions reordering (e.g.(?!a)(?=bcd)e==(?=bcd)(?!a)e==(?=bcd)[e--a]) and partial application (e.g.(?!a|bcd)e==(?!bcd)(?!a)e==(?!bcd)[e--a]). I think it should be okay. Adjacent assertions are rare in practice, and partial application has the issue that it might make the intent of the author less clear.
