22c5b13 (rebase -i: handle fixup! fixup! in --autosquash, 2013-06-27)

That's a noun that names a commit object.  What about it?

It's the commit that introduced the original change that's being clarified. Is a paragraph needed or simply "Ref commit: .."

I certainly misunderstood what this meant. It sounded like only one fixup! was
allowed per commit (i.e. one mistake) - fixing two mistakes wouldn't be
allowed. Hindsight is a wonderful thing.

I think this is about

Yes, but the original wording didn't make me think that.

git commit -m foo
... some other commits
       git commit -m 'fixup! foo'
... even more other commits
       git commit -m 'fixup! fixup! foo'

The last one is technically a fixup of the second one, but as long
as the second one is to be applied _and_ the last one comes after
the second one, we could say that both of them are fix-ups for the
very first one.  And that is what the original text says.

No. To me it said "You can only have one fixup (commit) for any given commit". So that's one original, and one fixup. After that the autosquash would leave the remaining fixup commits in their original positions in the commit sequence. Hence the patch.

I have a feeling that if the editor session to edit the todo drops
the second one and leaves this:

pick foo
       fixup fixup! fixup! foo

the command _should_ notice that the second one that is required to
apply the last one is gone and error out, but probably the code does
not do so, and if that is the case, I think "they fix the very first
commit that invited these fixups" is a more reasonable description
than the more technically stringent "fixup! fixup! is to fix what
the fixup! did", which is not what the code implements.

Also, does 'earliest commit requiring fixup/squash' fully convey that
its the one to fix.

I cannot tell if that a question or a statement?

It's a question. In your prior para you offer "they fix the very first
commit that invited these fixups" as an alternate.
It's when a users mental model is that they got their first fixup wrong and it's that fixup they are correcting, and later they add different fixups to the orignal that it all gets hairy. (diffs must have the right sequence, while snapshots don't care - so if we keep the diff sequence, we don't care about the user's mental model as the end results are the same).

The writeup needs to cope with the mental model rather than the end result.

It maybe that the whole 'fixup/squash' capability should be brought out as a small separate section to give space to these points and the user understanding.
