Is there a better way to make these edits?
Yes, make more substantive changes to the body of the post. Fix other things that are wrong, like spelling or grammatical errors, other formatting problems, adding additional tags, improving the title, etc.
This is standard practice when you don't have full edit privileges (and thus must have your edits approved by 2 other users who do have such privileges). Minor or trivial edits are discouraged when suggesting edits, and even if you got the system to recognize that you did, in fact, change something, you'd bump up against the requirement that you must make a substantial edit (defined as changing more than 6 non-whitespace characters) in order to submit your suggestion.
The idea is that since you're taking up time of at least two other users to validate your suggestion, and there's hardly ever a post that is otherwise perfect, you might as well make all of the other changes at the same time.
