I logged in this morning to find a notification about suggested edit on a post of mine (which by this point had already been approved): https://stackoverflow.com/review/suggested-edits/16492653. Ignoring the fact that the edit itself is mostly meaningless, the edit itself corrected a spelling mistake within a quote.
The quote itself is from this GitHub repository's readme and almost 2 years on the spelling mistake is still present:
At first I completely ignored the change, but now I've got to thinking: should I edit the post to re-introduce the spelling error (perhaps with a "[sic]")?
