The example says the skipped hashes are 0x00..., 0x66... and 0x22...,
and traversal-example.dot has 0x22... as the SKIP branch of D, but the
base64 proof ended with 32 bytes of 0x44, which is one of the VERIFY
hashes. Re-encode the proof with 0x22... as the last hash. The length
(101 bytes) and the tree serialization are unchanged.
```
sed -z -i 's/Author: /Authors: /' bip-0*.md
sed -z -i 's/Author: /Authors: /' bip-0*.mediawiki
```
Also align correctly in case of multiple authors.
```
sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.md
sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.mediawiki
```
After the scripted changes, the changes to BIP-40, BIP-41, and BIP-63
were undone, because it breaks CI.
These three BIPs only exist conceptually and their proposal documents
are missing which causes changes to them ot break the CI. I defer the
changes to these BIPs to a separate pull request to get CI to pass.
