Why should files end with a new line?
If content is added to the end of the file, then the line that was previously the last line will have been edited to include a newline character.

It comes from the C standard where you’re tasked to end all files with a newline (and you’re not allowed to escape that newline with a \ ). It makes sense; when the preprocessor concatenates files (or whatever the hell it does), a newline prevents two instructions from piling up on the same line.
Why is there a blank line at the end of a file?
Or, if he decides to add another portion of code at the end of file he can quickly do a GO and enter it instead of having to scroll until the end of file. Also, source control tools will report more changes if you don’t have a trailing blank line when you try to insert code at the end of file.
What’s the point in adding a new line to the diff file?
Since diff is line-oriented, it can’t indicate this by storing a newline for one of the files but not for the others — the newlines are necessary to indicate where each line in the diff file starts and ends.
