Scrolling, DEL, streaming

[01mf02]

Thanks for this cool project, and I'm happy that you're using jaq for it. :)

When holding the DOWN key to scroll down a list of values, the visible list does not follow the currently selected value. That means that when my terminal is H characters high, I can never see anything else than the first H values. I would have expected the currently selected value to be always visible on the screen.

Furthermore, trying to delete the character after the current one in the query with the DEL key does not have any impact. On the other hand, the backspace key works as expected.

Finally, I tried the query 0 | recurse(.+1), which yields an infinite stream of natural numbers. However, as soon as I typed the final ")", jnv froze (could not terminate with CTRL-C / CTRL-D) and after some time, my memory was exhausted, forcing me to restart my machine. o_O It would be cool if jnv could load output values in the background, thus remaining always responsive.

I'm using xfce4-terminal.
