Local echo + tmux horizontal panes

[elbaro]

When I have a tmux running two panes like this:

Pane1     | Pane2
prompt>   | prompt>

If I type 'hello' in the left pane's prompt, the panel separator | and the right panes' prompt> is shifted to the right by the same amount.

Pane1     | Pane2
prompt>hello   | prompt>

Though this is refreshed after a second, is this natural for a predictive local echo? can we make an exception for certain situations like tmux or screen?

Think it would be worth it to avoid moving (by deleting) any characters if there's several spaces between strings?

I recorded a quick video to show this. It's expected, but still annoying. Suggested methods for a fix?

Have a look at #622.

There's no good way to support this as we cannot reliably detect if the application is in insert mode, or overwrite mode. The default for readline is insert mode, which is why you end up with things shifting to the right.
