2014-07-02 Mark Majeres <mark@engine12.com>
* src/text.c (undo_cut, redo_cut, update_undo): Handle the
cases of cutting-from-cursor-to-end-of-line properly.
* src/nano.c (do_input): Don't preserve the cutbuffer when
CUT_TO_END is toggled -- it would intermix two cut types.
2014-07-02 Benno Schulenberg <bensberg@justemail.net>
* src/proto.h: Add a typedef for a pointer to a function.
* src/global.c (func_from_key): New wrapper.
