This addresses two discussion items:
- The list of UTXOs should not be interpreted as a "proof that no other
UTXOs for an address exist".
- The BIP only addresses "signer receives funds with the address" and
not "signer sent a previous transaction" use case.
This re-formats the document for easier editing and diff viewing.
Wiki syntax is weird for lists and line wraps break them. Simple lists
were changed to <ul> or <ol> tags but complex lists remain as they are
to not bloat the diff too much.
Before this commit it was not clear that non-native SegWit outputs
(e.g. P2PKH or P2SH-P2WPKH) only work if the correct scriptSig is
provided.
This then also makes it more clear why P2SH-P2WPKH outputs are NOT
supported by the "simple" variant.
This commit adds a table that clarifies what script types are compatible
with what signing variant and also makes more clear what the exact
format for the signatures of the different variants are.
```
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.
