* src/text.c (do_undo, add_undo): When undoing a Backspace at the tail
|
||||
of the file and nonewlines is not set, then don't add another newline
|
||||
but just reposition the cursor. Also, when doing a Delete at the tail
|
||||
of the file, don't add a superfluous undo structure. This prevents
|
||||
the appearance of an extra newline when undoing the Backspace/Delete.
|
||||
Patch partially by Mark Majeres. The problem was first reported in
|
||||
https://lists.gnu.org/archive/html/nano-devel/2015-06/msg00003.html.

* src/winio.c (edit_draw): Add some debugging code to track which
|
||||
multidata codes (for multiline regexes) get assigned to which lines.
