...

... and a lot more.

I am not sure if this relates to problems about my own configuration, or it is a bug/incompatibility.

What I expected to happen

Ugh. Compiled and installed Vim 8 and problem solved. Ubuntu 16.04 still has the several-year-old vim 7.4 as the newest vim and this is the problem.

Hey, thanks for reporting!

That's still good to know. That little filter method can probably be refactored for better backwards compat 👍
