Fix defaults & help text in command.js & README.md

- remove redundant default values
- add missing version specifier to README.md
- other improvements to consistency in README.md
- fix some defaults in the programmatic usage options

with the CLI help text in README.md adjusted by the following command:

    node ./cli.js  --help | sed 's/\[/</g' | sed 's/\]/>/g' | \
      sed 's/\"/\`/g' | sed 's/default:/Default:/g'
