I thought it made sense to return the same error description, expected '}'..., rather than introducing a new one, as it's the actual underlying error. I added a suggestion to reorder the format parameter if a #/x/X character is spotted afterward. However, I completely understand if the preference is to add a new error message similar to the approach taken in the previous PR this one replaces.

For future reference, we prefer not to ask questions of the user anymore. If I were writing this message, I'd say something like "you might have meant to write #?".
