mosh: --predict-overwrite option on the client

[kamaln7]

The official mosh client added support for the option “--predict-overwrite” a while back. What this option to my understanding does is overwrite the current line/command with the predicted text rather than insert it to the right of the cursor.

Using fish shell and the default prediction behavior is really not a great user experience, to the point where I find it unbearable myself on high latency connections—see https://github.com/mobile-shell/mosh/issues/932. Turning on “--predict-overwrite” is such a huge improvement. It would be really great if Blink supported this option!

Thank you!

We need to port that part.
