Incorrect keys behaviour after Esc

[Djaler]

Steps to reproduce:

1. Open Terminal
2. Press Esc
3. Press a

Expected: a typed Actual: like "Enter" key pressed

Another example: Press p after Esc -> works like an Up key

Is this issue still happening as described?

In master, I find that Esc then a does nothing; Esc then p produces a ":" character the first time else it produces ^[p

I am not sure this is a bug of elementary.terminal. Mate Terminal behaves the same, so is probably a "feature" of Vte.Terminal

We could ignore Esc characters if that was considered appropriate.

[Djaler]

Yeah, I think we could do it

There does not seem to be any consensus within elementary whether #263 will break anything or whether the current behaviour of Vte is intended. In view of that I suggest this issue be raised upstream initially with the Vte developers.

I will withdraw the proposed fix for now.
