I realize this is in fact unchanged from the original, so is not exactly
material of these series, but what is the meaning of "direct ancestor"?
Is it just "parent"?

Excluded when --ancestry-path is applied to what commit, exactly? To the
commit being considered for rebase, or to the <upstream>, or to the
'fork_point'?

Please notice that rebase claims to operate either on <upstream>..HEAD or
'fork_point'..HEAD range, and --ancestry-path without arguments applies
to the left commit of the range when used in "git log".

Looks like some clarifications are needed here, even though maybe not in
these series?
