In switching to title case for help headings (#4123), it caused me to look at "subcommand" in a fresh light. I can't quite put my finger on it but "Subcommand" looks a bit sloppy. I also have recently been surveying other CLIs and they just use "command" as well. All of them are commands anyways, just some are children of others (subcommands) while others are not (root or top-level commands, or just command). Context is good enough for clarifying subcommands from root commands. This is part of #4132
