Fix setting width greater than the default (#154)

Resolves #152.

It looks like a coding error when porting snakeyaml-engine to Kotlin.
The original project contains:

https://github.com/krzema12/snakeyaml-engine-kmp/blob/04614c75c124d30c58221ab11255c5d45d913a14/src/main/java/org/snakeyaml/engine/v2/emitter/Emitter.java#L213-L216

which I'm reimplementing in this PR.

BTW, there's no unit test for this behavior in snakeyaml-engine, and
ideally we'd like to add it there as well. It would have prevented this
regression.
