Split some show/hide messages?

Sorry, I don't know much about programming. You mean that implementing what I suggest is way more complex than just toggling e.g. [Show minor edits|Hide minor edits] in place of toggling [Show|Hide] and removing what's after (minor edits) as that would be toggled too inside the new messages?

Are there any other suggestions in case of that sort of grammar issues?

Consider using a format that doesn't cause grammatical issues.
