I sometimes see a question that needs a little code formatting (maybe a line of code escaped the code formatting tab/apostrophe). But when I try to edit it, I get a message the the edition couldn't be submitted because I have to change at least 6 non-space characters.
The thing is that there aren't any other changes needed in it, the only thing it does need is the code formatting.
What I sometimes do is add a few words (that aren't really needed, but they don't harm either, like in this question), and the the edit is submitted. But I don't like this method - I'm artificially adding words just to get the real edit submitted. Is there anything that can be done about this?
