Re: [RFC/PATCH 0/2] merge-base: add --merge-child option

Although I realised after
sending my mail you could also use

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

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.
