When the patch is not a merge commit, commit_hash is empty.
Quoting it as "${commit_hash}" passes an explicit empty string
to git show, causing:
fatal: ambiguous argument '': unknown revision or path not
in the working tree.
Remove quotes so the empty variable expands to nothing, letting
git show default to HEAD. Also align grep flag with the upstream
Nova version (-qi instead of -qxi).
