During an earlier iteration long time ago, as we knew Perl is
capable of handling sequence of bytes including NUL, it was decided
to start more strict by rejecting binary for all languages, which
can later be loosened, to limit the scope of the initial
implementation.

That's horrible. Thanks for noticing.
We'd want to catch segfaults from both hash-object and update-ref.
One way to do so may be
O=$(git hash-object -w blob1) &&
git update-ref refs/myblobs/blob1 "$O"
Thanks for a review.
