Minor nit: but when I wrote the code for run_rebase() I separated the
options for "Shared options" and "Options passed to git-rebase" into
different code block groups from the other code, and I would like it
if it remained that way :-(

Hmm, interesting. If rebase.autostash=true !opt_autostash, we don't
need to pass --no-autostash to git-rebase because it will only stash
if the worktree is dirty, but a dirty worktree will be caught by
git-pull's die_on_unclean_worktree() anyway.
Still, it may be a problem because the worktree may become dirty
in-between our "worktree is clean" check and when git-rebase is run
(during the git-fetch), and the user may be surprised if git-rebase
attempted to stash in that case.
So we may wish to pass "--no-autostash" to git-rebase as well.

Git code style puts the else on the same line, not on a new one.

Yeah, I agree with Eric that this comment should be dropped,

and these error messages combined.
