$table_prefix should be validated upon entry
|Reported by:||johnl1479||Owned by:||dd32|
It appears that $table_prefix is validated to only contain letters, numbers, and underscores.
However, the user is not made aware of this requirement until after the wp-config file has been created.
If the user tries to enter a hyphen or other non-acceptable character, they should be alerted to this and be able to fix it before wp-config is generated.
