Subject: Add sanity check for wrong uses of check_hash
X-Git-Url: https://repo.or.cz/w/dowkd.git/commitdiff_plain/262034b5b19398a53152f17508724fc88a9d67c7

Add sanity check for wrong uses of check_hash

This catches bugs in the script which might lead to false positives.
It's a purely defensive change, no such bugs are currently known.
