Ed Page 9f9e410c6d feat(complete): Minimal rust-completion
Inspired by argcomplete, this provides Rust-implemented completions
- Only bash for now
- No subcommand support
- No flag value support
- No special settings support
- No handling of positions within positionals
- No prioritizing of required or removing of conflicts (including
  self-conflicts)
