Hi Andrii,

The patch looks good to me. Some minor nits:

It's missing a colon after "NEWS" (":").

The fact that there is completion here is incidental. I'd omit that from 
this particular place in the manual.

Branch or revision? I understand that in practice the difference is 
minimal, but we should pick one or the other wording and use it 
consistently. Here, in the functions' docstrings, and in the prompt 
string as well.

I'd prefer "branch" since it's usually what someone merges, but saying 
"revision" everywhere should also be okay.
