Insert a missing 'not' word in a negative sentence.
  ... but are [not] reachable from neither A or C.

There's a peculiarity of the English language here that means you
should not use the word "not". The actual error is using "or" as
the conjunction, instead of "nor": the construct should read
"neither <alternative 1> nor <alternative 2>", and it means that
both alternatives are rejected.

But it's not the same to say "not reachable from either A or C", and
"reachable from neither A nor C". In the latter if a commit is reachable
from X (or anything other than A or C), it should be included.

So A~ would be included, because it's reachable from B and reachable
from not A (i.e. B).

It should be "not reachable from either A or C".

Cheers.
