OK, so make "rebase in C" a faithful conversion of the original, the
code that lead to builtin/rebase.c:261 must be fixed not to pass a
shortened oid. I suspect that internally it has a full object name,
so not shortening would be the right thing anyway, so regaredless of
this bug, it probably makes sense to do the fix.
But as you said, even the scripted version that passed the full
object name had a (10/16^40) chance of using a 40-hex that only has
[0-9] and caused the same breakage, so such a change to "rebase in
C" is sweeping the age old bug under the same rug, in the context of
discussing this particular bug.
I agree with you that it is a better fix to the problem to allow the
caller to say "I am giving an oid---it may (or may not---I do not
even bother to check) consist of only digits, but do not treat it as
an index to the stash reflog."
