I would like to have a configuration option so that every files I save ends with a newline on every line, including the last line.
It has been considered a good practice in the Unix/Linux world that every lines end with a newline character. Some editors like Vi don't even propose a choice about this.

Reproducible: Didn't try

Steps to Reproduce:
1. Open Kwrite
2. Types: Line 1<ENTER>Line 2
3. Save the file as "demo.txt"

Actual Results:  
$ od -a demo.txt
0000000   L   i   n   e  sp   1  nl   L   i   n   e  sp   2
0000015

$ wc -l demo.txt
1 demo.txt

Opening the file with vi, it warns that the current file has no EOL:

"demo.txt" [noeol] 2L, 13C

Expected Results:  
$ od -a demo.txt
0000000   L   i   n   e  sp   1  nl   L   i   n   e  sp   2  nl
0000016

$ wc -l demo.txt
2 demo.txt

Saving the file with Vi will add the missing newline character.

Reopening it with Kwrite and showing line numbers, the content is displayed with 3 lines:

1| Line 1
2| Line 2
3|

It looks like a unique newline at the end of a file is interpreted by Kwrite as an empty line.
