Hmm, tricky but correct to do the "< 1" comparison. If the file
does not exist, you'd get -1; if it fails to read it, you'd get -1;
if it turns out to be empty, you'd get 0.

The original is
rev-parse --quiet --verify "$1^{commit}"
Unless the caller of this function already appended "^{commit}" to
whatever the user gave "bisect--helper bisect-reset", this
conversion is not equivalent. If you said
git bisect reset HEAD:
get_oid() would tell you that the top-level tree object of the
current commit exists in the object store, but the original is
meant to catch "That's not a commit, it's a tree!" before attempting
to run "git checkout" on it.
I think get_sha1_committish() is what you want to use here.

Also this version fails to catch "bisect reset a b c" as an error, I
suspect.
