The commit message doesn't call this out specifically; instead it appears to have been to address double printing to the console while in ddb. I noticed this because a ddb script which previously resulted in some things ending up in a textdump's msgbuf.txt no longer does so. It may be that the answer is "use db_printf in ddb", which is ok, but I thought I'd check anyway to see if the aforementioned change was indeed intentional, since I wasn't able to dig up any discussion about it.
