parse command line like Bash

The goal is to turn a string like command "arg one" arg2 arg\ three into a string of tokens like ('command', 'arg one', 'arg2', 'arg three').

(Don't get confused — the goal here is not to start with @ARGV and do further processing, similar to Getopt::Std; there are a million modules for that already.)

can only parse a single command

• Text::ParseWords's shellwords() (2022)
• Command::Bash's parse_cmdline() (2022)
• Parse::CommandLine (2014)
• Parse::CommandLine::Regexp (2020)
• Text::Shellwords::Cursor (2012)
• (list in Acme::CPANModules::Parse::UnixShellCommandLine)

can parse multiple commands separated by semicolon, or do redirection

• Shell::Base's parseline() (2004)
• Shell::Parser (2005)
