Fix add_history usage in down arrow handler

Browse Source 
[Programming with GNU
History](http://www.math.utah.edu/docs/info/hist_2.html) mentions
using_history().

Chet, maintainer of readline told me about it. (Thanks Chet!)

Seems like we need to call this so that the history offset is at the
right end of the list. I assume it's called in the linehandler
automatically.
