Description:
There are weird exit codes of some utilities:

`mysql_waitpid --help` returns 255 instead of 0

`mysqladmin --help` returns 1 instead of 0

both of them accept '--help' (or '-?') as valid option according to the documentation

How to repeat:
$> mysql_waitpid --help &>/dev/null
$> echo $?

$> mysqladmin --help &>/dev/null
$> echo $?

Current resutls:
255
1

Expected results:
0
0
