This is the only thing from your latest patch that I included into
1.7.6-jumbo-7 for now. While doing so, I noticed that you seem to have
forgotten to add a license to rawSHA1_fmt.c - it has your copyright
statement, but no license. I'd appreciate it if you correct that with
your next patch update.

Sounds great, but unfortunately this is unreasonable to include in the
jumbo patch as-is (since it will break things for many people). Maybe
I'll need to start maintaining this as a separate patch to be applied on
top of jumbo patches... until we have a more official solution.
Thanks,
