update nano/editor

this updates nano to latest version
Changelog:

- After a search, the spotlighting is dropped after 1.5 seconds (0.8
seconds with --quick) to avoid the idea that the text is selected.
- A + and a space before a filename on the command line will put
the cursor at the end of the corresponding buffer.
- Linter messages no longer include filename and line/column numbers.
- Color name "grey" or "gray" can be used instead of "lightblack".
- The color of the minibar can be chosen with 'set minicolor'.
