Review comment:
Thx @rmannibucau for the follow up!
Yes - testing with `contains` is a simplification and neglects some weirdo
cases... and yes: it would require char, position + offsets to properly test
and replace the closing and opening brackets.
Thus, I like the idea of using `PropertiesLookup#lookup` and returning the
key there. The parsing "magic" (char, position, offsets) is already done in the
substitutor, so I guess fallbacking there is a good option.
I will take a look at it.
