Generally, rebasing does not necessarily implies =E2=80=98git gc=E2=80=99, = so I think one has to be unlucky to have the former commit disappear right away, no? But yeah, I don=E2=80=99t think there=E2=80=99s much we can do. Or perhaps= we could have =E2=80=98commit-relation=E2=80=99 report 'unrelated when one of the co= mmits does not exist, that=E2=80=99d be clearer and more useful than this error. WDYT? Ludo=E2=80=99.
