which looks like we're having to repeat ourselves because it's not
paying attention...

You are half wrong; "--left-right" is about "do we show the </>/=
marker in the output?", so it is true that it does not make sense
without "...", but the reverse is not true: A...B does not and
should not imply --left-right.

The repetition I meant is that by the definition of ancestry-path, the 
above would seem to be equivalent to

   git log --ancestry-path --left-right E F --not $(git merge-base --all E F) $(git merge-base --all E F)

Anyway, revised separated-out version of the patch follows.
