This patch version addresses:
- extra test for number of arguments in the header t9001 test
- removed use of envelope in the documentation
- re-arranged the validation loop and surrounding code to be closer to
  the other code not in functions
- made a note in the commit message that the moving of validation later
  can have some difference in stdout compared to before but actual email
functionality should be ok

Hopefully this looks better.
