source: global.c @ b31252d

release-1.8release-1.9
Last change on this file since b31252d was 5f8ec6b, checked in by Nelson Elhage <nelhage@mit.edu>, 11 years ago
Replace per-editwin killbuf with a global one. Right now, the kill buffer is part of a struct _owl_editwin, which means that it goes away when the editwin does - rather inconvenient if you realize mid-paragraph that you're sending to the wrong class. This patch adds a global for the killbuf (and its accessors), modifies the editwin kill/yank functions to use it, and removes the old per-editwin killbuf.
