commit 1daac74f63836c9eeb98e53e77d69180698eef5e
Author: Raymond Toy <toy.raymond at gmail.com>

    Clarify a few things.
    
     * Change check for id to be 1 <= id <= 3, and print error message if
       it's not true.
     * Add comment that we're "intentionally" writing past the end of
       segname because we're trying to fill out the rest of the
       segment_command.
     * Fix typo in sentence.

    Don't leak the string created by strdup.
    
    Probably harmless if we do since we exit(0) at the end.
