linenoise: don't process carriage returns in history.

* linenoise/linenoise.c (lino_hist_load): Don't look for
and overwrite carriage returns with the null character; only
do that for newlines. We already handle embedded carriage
returns just fine by displaying them as ^M.
There is a plan to use these characters for breaking up lines
in an enhanced multi-line mode.
