In parentheses, as a suffix. In the option string, "ab(longforb)c".

Need to check for "=" as part of the match or else you also match on
longer environment variables that start with this name as a prefix.

If you tell it to print an environment variable that doesn't exist,
return code should be 1.

Fixed a typo in the help text.
