Moving cursor up down on multiline command with wrapping

[jcubic]

Expected behavior

When command have more then one line and those lines split into more lines I expect up/down to work correctly

Actual behavior

it jump and not move into position of splitted line visibile on terminal but original lines that user type
so basically it only handle real line breaks and not terminal wrapping.

Steps to reproduce

1. Enter text with multiple lines
2. Resize the terminal to make lines break into additional lines
3. Try to move cursor up/down
