The only mention of this that turned up in a quick search was a passing mention three years ago. I've just encountered a pending edit on this question where the editor tidied up the question with MathJax and such, but also proposed to change favored to favoured.
My habit when I make edits is to leave such spelling variations alone, along the lines of the (paraphrased) "edits should change the voice of the author as little as possible" philosophy of SE. I see three options for reviewing this proposed edit:
- Accept: The edit is otherwise perfectly desirable. But, if I were OP, I would be annoyed at having my perfectly fine (to me) spelling changed, and having to make a one-character edit to take the 'u' back out
- Reject: This seems awfully harsh to the editor, and tosses out a perfectly healthy baby with some vaguely dirty bathwater
- Improve Edit: Probably the best option,
but then I snipe the edit-credit from the edit proposer.especially since I will not, in fact, snipe rep from the edit proposer. (This is the route I took, seeming least objectionable.)
So: What is our policy regarding such style considerations?
