Description:
The --read-only option doesn't seem to appear at all in the manual, other than a changelog entry in MySQL 4.0.14.

How to repeat:
-- run the command
SHOW VARIABLES LIKE 'read_only';

-- Check out the show variables page or the SET page.
-- Notice that the variable isn't on there.

Suggested fix:
1.  Add the variable listed to the SHOW VARIABLES section.  Something similar to the change log should be fine:

read_only Available from 4.0.14. Causes mysqld to allow no updates except from slave threads or from users with the SUPER privilege. 

2.  Add it to the dynamic system variable section.

read_only  BOOL GLOBAL

3.  Possibly add a mention somewhere in replication since that is where it is useful.

I will do the SHOW VARIABLES part and when it's done I'll forward the rest to the docs team.
