I suspect that your concerns about git-blame could be resolved by adding this commit to .git-blame-ignore-revs. From a long-term perspective, I think standardizing on the trailing comma style will actually improve git-blame because patches won't need to add a comma to the previous line when adding a value. Committed that way.

Yeah, that's a good point. I had been leaning towards "this is unnecessary churn", but with that idea I'm now +1. +1. It's a fairly common practice in Perl code, too, and I often do it for exactly this reason. cheers andrew -- Andrew Dunstan EDB: https://www.enterprisedb.com
