Expand the reference to commits like so:

    15a147e618 ("rebase: use @{upstream} if no upstream specified",
    2011-02-09)

Also pay attention to the subject, in which it is unclear whose
argument "op_prep" is.  Other than that, your rewrite is more
readable than the original.

    The error_on_missing_default_upstream helper function learned to
    take op_prep argument with 15a147e618 ("rebase: use @{upstream}
    if no upstream specified", 2011-02-09), but as of 045fac5845
    ("i18n: git-parse-remote.sh: mark strings for translation",
    2016-04-19), the argument no longer is used.  Remove it.

Yes, with s/should/could/.  I agree with you that we should leave it
as-is.
