You can make this yourself with a wrapper script: let the script trim any trailing newlines after the real nano exits.

Or you could apply the attached patch to your private nano and have nano always trim trailing newlines.

It's too small a thing to add an option for, and it cannot be the standard behavior -- not all people will want it.

This following crosstable describes the behaviour I'm imagining:

| # of trailing newlines | set autotrimtrailingnewlines | unset autotrimtrailingnewlines |
|------------------------|------------------------------|--------------------------------|
| set nonewlines         | always 0                     | don't care                     |
| unset nonewlines       | always 1                     | at least 1                     |

Oftentimes during editing we accidentally add extraneous new lines to the end of my file.

In most if not all situations that I know of, there's no reason to keep those trailing linebreaks. So I think it would be a good quality-of-life improvement to have an option in `nanorc`, something like `set autotrimtrailingnewlines`. It should also work well with `set nonewlines` without too much trouble.
