bip-0141: clarify the sigop count calculation for CHECKMULTISIG 
Since the sigOpCount calculation was copied from P2SH, and P2SH
restricts the use of CHECKMULTISIG with pushed integers the reference
implementation would not take into account the number of public keys for
17 to 20 keys (not representable with an OP_N) even for P2WSH.
Therefore it fallbacks to accounting for 20 sigops in this case, which
this sentence seemed to mismatch with.

Btcd and Libbitcoin use the same calculation as in Bitcoin Core.

83596de8ca bip141: Change 'block cost' to 'block weight' 
The term 'block cost' led to confusion about the unit that it is
expressed in, in that it expressed monetary cost. Change it to a more
general term 'block weight'.

This was discussed in the [2016-07-14 Bitcoin Core developer meeting](http://www.erisian.com.au/meetbot/bitcoin-core-dev/2016/bitcoin-core-dev.2016-07-14-19.00.html).

d72c1bfc71 Update bip-0141.mediawiki 
The byte representation of "<0 <32-byte-hash>>" is "0x220020{32-byte-hash}"

What was listed here would be the byte representation of "0 <32-byte-hash>". The text explains that there is only one item in scriptSig, so I'm guessing the byte representation is wrong. Also the corrected byte representation would produce the same sig/pubkey described in P2WSH after following the bip16 rules.
