Hyphenate words, and always expect double dashes for long options. A small number of options have entirely new names. In general I have added aliases for the unhyphenated and single-dashed varieties, and used mflag's deprecation syntax to make it print a warning when it sees them. I left some abbreviated options unhyphenated (e.g., `bufsz`), and the TLS options as-is since they correspond with Docker options. NB the deprecation wanrings will mostly get printed to container logs, since mostly the executables are run in containers. The next step is to emit warnings from the script for the options mentioned in the script usage message.
