That's the only way I was able to duplicate it. I think that's a feature. Yes, but not with ChangeLogs in specific. Anything font-locked takes longer to be font-locked after a revert because it appears to be doing it twice. I thought I fixed this at some point, but it does not appear to be working optimally now.
