Description:
In MySQL 5.1, the --master-xxx replication options are deprecated and if used result in a warning to the error log. However, the warning is unhelpful because it does not specify which option resulted in the warning.

Start a replication slave with a --master-xxx option. For example:

[mysqld]
master-port=12345

Then look in the error log. It will say:

[Warning] 'for replication startup options' is deprecated and will be removed in a future release. Please use ''CHANGE MASTER'' instead.

It should say this:

[Warning] '--master-port' is deprecated and will be removed in a future release. Please use ''CHANGE MASTER'' instead.

How to repeat:
See above.

I notice this warning appears only once, even if multiple --master-xxx options are used. Perhaps the server is just keeping track of whether any such options are used and this warning is supposed to be a generic warning. In my opinion, it would be more helpful to see a warning that names the offending option, one warning for each such option.

Verified as described in 5.1.50.

This bug is only repeatable on 5.1, not 5.5 and trunk.
Since this bug is triaged for trunk, I'm closing it as "Can't repeat".
