The second commit has nothing to do with autoclosing really, its indenting after brace and as such should be a separate PR
And it needs to be documented in the manual not (or as well as) the commit message.
I agree with @elextr here. I'm open to both improvements presented in this PR, but the second one should be a separate PR. So let's focus on "consume closing chars when typing them manually" for this PR please.
I have also conducted what Notepad++ does in that regards, and it's definitely better than what we do.
