Any system that has an EDITOR which includes spaces isn't worth supporting. Doubly so because you have a reasonable use-case that makes quoting it the wrong thing to do. Bourne shell scripts will always have to make certain trade-offs between portability and readability. You could make the script massive and try (and fail) to cover every eventuality, and it would get more and more horrible and fail in more and more subtle ways. Supporting diverse stupid systems is what made the GNU code as crazy as it is (arguably that helped it gain dominance back when there were so many different and incompatible unix systems, happily that's no longer the case today).
