I was more worried about scripted Porcelains, like : "${GIT_OBJECT_DIRECTORY="$(git rev-parse --git-path objects)"}" which I think can safely lose the outer dq pair. In t/ directory, there is this one in test-lib-functions.sh which I do not offhand know how these problematic shells would handle. echo "#!${2-"$SHELL_PATH"}" && Other than the presence of these two that are not covered by this patch, the patch itself looks good.
