OK, yes, please change it back, then. Having BLID here is of course
incredibly convenient, because we can avoid all kinds of difficulty
in decoding the logs. The decoder really prefers having this, and
then it does the right thing.

I've tested log decoding with this series and it is working nicely,
btw.
