By the feature request mention in #2023

Thanks! I'll notify the people in that issue about this effort so that they can test it.

Looks fine for me. There is FIXME comment in both files (line 95 and 112), witch could be removed.

@pitkonst , let me know if any more change needed,
I didn't add the parameter to the config file as it is optional,
let me know what is the project policy about it,
should I add it in the doc and sample config files...
thanks again ...

About project policies we better ask @lminiero

[lminiero]

A commented value in both config files (just to let people know it exists) would definitely help. You can use the existing lines as a template for the new property. I also noticed your patch has a lot of empty lines in between code snippets, so please just keep one for those (even though it's an easy nit I can fix myself after merging).

[lminiero]

Thanks for the quick fixes! This seems good to merge for me: unless I see any objection on the original issue, I'll merge tomorrow morning 👍

[lminiero]

I don't see any objection, so I'll merge, thanks again! 👍
