request: support standard navigation keys: arrows, home, end, etc.

[dan-da]

Probably this feature is already planned, but I will request it just in case.

Running the dummy example, if I try to use any navigation key such as an arrow key or home key, then ugly control chars are printed instead. example:

help^[[D

I was expecting/hoping that standard nav keys would work, eg:

left/right arrows for navigating text up/down arrows for cycling through history home/end for begin/end of line ctrl-a / ctrl-e for begin/end of line
