Subject: [PATCH] main returns 0 upon normal ternimation

The return value for main should indicate how the program exited. Normal
exit is generally represented by a 0 return value from main. Abnormal
termination is usually signalled by a non-zero return but there is no
standard for how non-zero codes are interpreted
