These are most likely introduced by #92, which I worked on earlier.

Problem

Cursor position update

Potential Culprit

Potential Fix

• Probably this function should handle the update to the cursor.
• Afterwards, if there is a char insert we copy over the history result to line_buffer.

Problem

Last entry is not shown

Potential Cluprit

hitting back calls the previous history, which increments the cursor position.

Potential Fix

display first then perform move. Thoughts?

Problem

History command disappear after few seconds

I am not sure why this could be happening. Probably the clock update flushing history traversal state.

I really should have added more tests to engine as well

git stash ; git stash clear
cargo run
