LGTM, thanks

Can you just squash the commit in a single one?

Thanks!

Looks like I'm holding the tool wrong. The Github desktop app is complaining "Unable to squash. Squashing replays all commits up to the last one required for the squash. A merge commit cannot exist among those commits."

Feel free to either squash this PR on commit, or re-manufacture it as appropriate.

Yeah, this is because merge and squash are mutually exclusive, and maybe I'm too biased with the squash to maintain the history clean.

Anyway, to keep you as the author of the commit, I remove just the merge commit and change the commit message. Otherwise, if I will squash, you lost the authority on the commit.

Thanks to contribute in this repository :)
