I suspect you misread what I wrote (see below for the patch).
The fixup_count is a new local variable in update_squash_messages()
that holds N+2; in other words, I am not suggesting to change what
opts->current_fixup_count means.

I actually do not mind to go with what you originally sent, unless a
cleaned up version is vastly more readable. After all, a clean-up
can be done separately and safely.
Thanks.
