c6a995e Improve readability of DecodeBase58Check(...) (practicalswift)
Pull request description:
Use the more readable form ... ```c++ &vchRet[vchRet.size() - 4] ``` ... instead of ... ```c++ &v.end()[-n] ``` Has the added benefit of eliminating a spurious static analyzer warning about improper use of negative values.
