Rather than combining a bunch of conditionals in a single expression,
simplify by inverting the mergeability requirements into guard clauses.

that is - instead of checking what must be true for the conditions to be
met, instead check the inverse of the requirements and return false if any
are true, defaulting to true.

No functional change intended.
