Improve command substitution

- .kshrc file isn't special - $ENV can point to any file
- use $MAIL since is available by default
- replace backticks ('`') with '$()' - they both nest and look better
- be consistent about using `[` or `test` - chose the latter here
- use `-n` for the second test case in order to keep the examples'
  logic the same:

	[...] && echo '* '
