Bug #9835	mysqld_multi --help won't output help if there are parameter problems

Category:	MySQL Server	Severity:	S3 (Non-critical)
Version:	4.1.11	OS:	Any (Any)
Assigned to:	Jani Tolonen	CPU Architecture:	Any

Description:
If there are errors in the my.cnf file [mysqld_multi] section such as a parameter missing a value, the --help output will not display. This is a bit counterintuitive as the error that is output suggests using the --help option for help.

How to repeat:
1. Ensure the following is in your my.cnf

[mysqld_multi]
password=

2. Run mysqld_multi

3. Run mysqld_multi --help

Suggested fix:
Check validity of the configuration files after checking for --help.
