Thanks for doing this @yusuke-noda!

Relatedly, I released a change with 9.5.1 so that in a config file you can provide a two-item array directly instead of a single string to avoid the ambiguity of the splitting. But of course we'll still always need the splitting logic for the CLI.

I'll fully review and merge this shortly. Before releasing I might also add some deprecation warnings, because what I'd like to do long term is enforce quoting either side of the string if it contains colons, so we don't have to do such clever splitting with awareness of all the platform quirks.
