While intended as a playful error message, `Cheatin’ uh?` can be interpreted as insulting or accusatory in an already stressful situation. This replaces Cheatin’ with more meaningful error messages, depending on the error that occurs. Props ElectricFeet, EricMeyer, karmatosed, dd32, BandonRandon, melchoyce for language; dmsnell for original patch; peterwilsoncc. Fixes #38332. Built from https://develop.svn.wordpress.org/trunk@42648 git-svn-id: http://core.svn.wordpress.org/trunk@42477 1a063a9b-81f0-0310-95a4-ce76da25c4cd
