Is there a way? Yes, on meta or in chat.
There is no option for pinging editors like there is for users leaving a comment. Or ping them, thank you Makyen. Considering the editor here is a moderator, you can be about guaranteed he reads every meta. Just post it on the correct meta ;-)
For this particular edit, I've fixed it. Looks like an honest mistake to me. Jamal edits so many questions that this was bound to happen sometime. Not even he is perfect.
Leaving comments for every edit is not feasible and wouldn't have fixed the problem here. The "problem" here is comparable to a typo and commenting typos assumes we catch them during the edit. In which case we'd fix the typo, not comment on it.
Descriptions for edits are primarily useful for major edits, for people new to editing and everyone without instant-edit privileges. For minor corrections and readability upgrades while having privileges, it simply goes a lot faster if you don't worry too much about the description most people won't care about anyway.
In short, editors sometimes make typos, too. If you see an edit that is generally positive, but missed the mark by a bit, feel free to correct it. You won’t be stepping on anyone’s toes.
