In 2b9bd488ae ("completion: teach rebase to use __gitcomp_builtin", 2019-09-12), the completion script learned to complete rebase using __gitcomp_builtin(). However, this resulted in `--onto=` being suggested instead of `--onto `. Before, when there was a space, we'd start a new word and, as a result, fallback to __git_complete_refs() and `--onto` would be completed this way. However, now we match the `--*` case which does not know how to offer completions for refs. Teach _git_rebase() to complete refs in the `--onto=` case so that we fix this regression.
