Bug details

Describe the bug

When an array of data is inserted into the config file the above example is written out as

        replicate-ignore-table = ['core.table1',  'core.table2', 'core.table3']

This isn't a valid format for mysql configuration.

Steps to reproduce the bug

Expected behaviour

The output should be as follows.

replicate-ignore-table                  = 'core.table1'
replicate-ignore-table                  = 'core.table2'
replicate-ignore-table                  = 'core.table3'

Attempts to fix the bug

I've fixed it in a PR I'll be posting shortly.
