Author:

Erik Nygren <nygren@mit.edu>

Branches:

master, barnowl_perlaim, debian, owl, release-1.10, release-1.4, release-1.5, release-1.6, release-1.7, release-1.8, release-1.9

Message:

* 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.
