Quoting problem in mysqld_multi

[Nicolas Baradakis]

I think there is a problem when mysqld_multi builds the command line
which starts or stops an instance of mysqld. If the value of an option
in my.cnf contains a metacharacter of the shell, weird things happen.
For example, a '>' or a '|' in a password raises errors.

Putting quotes around options in the command line should be a wise
thing to do in this case.
