Is this change released?

I ran into it, and so has someone else recently (https://github.com/mysql/mysql-utilities/issues/40 )

If it hasn't been release, it may make sense to use:
values['extra'] = " %s" % col_data[_COLUMN_EXTRA].upper()

instead of:

values['extra'] = " %s" % col_data[_COLUMN_EXTRA]

(to be consistent with the way other column options are formatted)
