Description:
"Reverts never cause an edit conflict - if between you pressing edit, and then
pressing post, someone else edits the page, their edits will be silently
overwritten (though still in the page history). Beware of reverting high-traffic
pages! Conversely, if it looks like someone has deleted your edits, consider if
it's more likely that it's one of these unfortunate reversion conflicts."
