DISCLAIMER: I am Maika-san, the one who made the edit.
I'll have to disagree with David Bowling here. We all know that Cdim7 and Cm7♭5 chords are not the same, because Cdim7 has the notes C-E♭-G♭-B♭♭ while Cm7♭5 has C-E♭-G♭-B♭. A dim7 chord has no other name, but a m7♭5 chord is also known as half-dim7 chords. In fact, I decided to edit the question out, changing Cdim7 to C half-dim7, as I thought if the OP just "typo-ed" C half-dim7 to Cdim7.
So I'll have to tell the truth that I believe rolling back was a bad idea. As David Bowling had said, it is still possible that the OP mistakenly thought dim7 and m7♭5 were the same. That's why I wrote, "if this isn't what you asked, change it, please," so the OP can change it if he / she disagrees with my edit. I regardless had a strong feeling that the OP actually meant half-dim7 but made a typo which caused all of the answers to "follow" the typo. If he / she agrees with my edit, the "Sorry, this question is wrong" comment would make sense. If my edit was actually right, the answerers can edit their answers to match the question.
So I would like to say it would be better to just go with my edit rather than rolling back, and let the OP be in charge of deciding to agree with it or not.
