Support for Git Bash (xTerm / mintty)

[Velociraptor45]

Hey there,

could you add support for the Git Bash console (that you get by default when installing on Windows)?
Getting the size has basically been done (I shamelessly stole most of this from here, around line 90)

const {execSync} = require('child_process');
var buf = execSync('tput cols && tput lines', {stdio: ['ignore', 'pipe', process.stderr]});
var sz = buf.toString().trim().split('\n');
if(sz && sz.length == 2){
    return create(sz[0], sz[1]);
}

I can create a PR if you want, however I'm not really a js-dev, so you might want to do this yourself.
