While doing a history merge of the article "Extreme programming" on the English Wikipedia, I had to use the "suppress redirect" right often while moving the page. However, when I did so (for example while moving the page from "Extreme programming/Temp2" to "Extreme programming", I got the message that said "A redirect has been created" rather than the normal message that says "The creation of a redirect has been suppressed". This was extremely confusing. I also got the same incorrect message when moving my sandbox at "User:Graham87/sandbox". I presume this bug is fairly recent because I have never encountered it before.
