no need to double escape a trailing $; $ by itself is not special in any way

removing and adding keys must be atomic

If we delegate this to multiple seprarate objects (e.g. using __line) and the
config run is interrupted after applying only some of them we may leave the
target in some random state.
We may have even locked ourself out of the target.

So remove and add keys ourself so either none are all changes are
applied.
