Is the patch still "on the table"?

Also with this patch, the attributes `start_string_prefix`,
`end_string_suffix`, and `parts` are only available after calling
``inliner.init_customizations(document.settings)``. 

Is there a use-case for this scenario we want to support?
If not, we could define them as internal auxiliary variables after
the API change that came with implementation of [ 103 ].

That said, I am not against the patch. If including, I just propose a small
correction:

No need to call the instance variable here, as we set it just some lines
above (overwriting an eventually existing instance).
