nano: upgrade 9.0 -> 9.1

Changelog:
==========
- When searching, the viewport is placed snug left where possible.
- The ability to read and write files in old Mac format was removed
  (that is: files that use a lone carriage return as line ending).
- The ^T toggle between WhereIs and GotoLine has been dropped.
- When --backup is active, in some situations no backup was made,
  or it had a wrong timestamp.  Both issues are fixed now.
- When nano crashes or is killed, any .save file is not chmodded
  to the permissions of the base file, nor chowned to its owner.
- M-Ins and M-Del have become rebindable.
