* Fixed preservation of e->dotsend across owl_editwin_clear().
* Added history for multiline edit windows (eg, for zephyr composition).
The M-n and M-p keys will cycle through the history ring.
In particular, it is now possible to edit the command line
of a zephyr being composed: C-c it and restart it
and then M-p to get the aborted composition back.
