@motemen @Songmu this is ready for review an merging.

Sorry I haven't reviewed this. I will look at it when I have some time. Please wait a little longer.

[Songmu]

It's true that smartcasing is a behavior we see a lot, so it doesn't seem like a bad idea to incorporate it. So I'm going to merge it.
However, since it is strictly an incompatibility fix, I may revert depending on the opinions of users. Thank you very much for your cooperation.
