I know quite a few posts with small mistakes involving less than 6 characters, but I can't correct them without some more changes in the post, because that "at least 6 characters changed" limit.
What to do with it? I can make some invisible changes in addition to the correction, but I'd be happy to know official Christianity.SE policy about this. Would something like this (click "edit" to read invisible text here) be OK? Is there any better option? Or can I consider it a "Christianity.SE low-ranking editor's marginal edit policy"?
