I tested the editor briefly and it looks really promising, thanks for
the hard work! Vis looks like something that I hoped neovim would evolve
into eventually...

In my brief testing I found that H, M, L (in Vim: moving the cursor to
the first, middle or last line of a window) are not implemented and that
G does not move the cursor to the end of the file yet.

In general, are patches that modify vis' cursor movement or operator
behaviour to be closer to that of Vim welcome?
