strange behavior opening a :term: open 2 new tabs

[jerabaul29]

There is a strange behavior when using the :term command: it looks like 2 new tabs get created, 1 is the terminal, 1 is an (additional) view of the window from which the terminal-opening command was issued. See screenshot (there are 2 tabs in the bottom half: 'welcome' and the terminal. Both were opened by the :term command while I would want only the terminal, it is strange to need to close 2 tabs when done :) ) :

Also experiencing this, also, not sure if related, but when tabbing between windows, Welcome is still there while not visible anywhere on screen and tabbing to it creates a new tab with it.

That's a different issue @lessp. See #1192. But this issue also applies to splits generally, not just terminals. The underlying problem is a bit of a chicken-and-egg one: You can't create a split without a buffer, and you can't create a buffer without it automatically opening a new editor since libvim currently isn't able to distinguish between buffers being open internally, buffers being opened externally and already opened buffers being switched to. They all just emit a BufferEnter event. So i think the proper fix here is to have libvim emit more fine-grained events.

Would it be possible, as a temporary fix, that the :term command 1) split opening a new buffer as this is necessary, 2) opens the terminal in the new split 3) close the un-used buffer? Of course this is a relatively ugly patch, but would make things much more usable.

Was looking at this along with #3150 - looks like this no longer reproduces
