I see.
It's quite unfortunate that I allowed unquoted strings in
the configuration, so this complicates the checking for boolean a
bit. I am thinking of disallowing unquoted strings in the next
release, hope there's no big fan of this. Is there?
I don't any problem here. I think enforcing quotes for strings is a
good thing. If the config parser find unquoted strings, it should
generate an error and fail to parse the config.
