Last change on this file since 10b866d was 10b866d, checked in by Erik Nygren <nygren@mit.edu>, 19 years ago
* 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.
