What do you mean by "some confusion". The format used is perfectly valid...

The format is perfectly valid, no doubt. Many line-based tools however do

1. complain about incomplete last lines (diff and related tools, editors such as vi),
2. will make things harder to read ("cat" on the file will interfere with the next shell prompt),
3. will do something wrong (some regular expressions, perl's chop),
4. silently append that newline (sed, grep, vi, …),
5. which in turn makes it hard for diff and related tools (including version management software) to see whether anything has changed at all.

Unless there is a reason against having this terminal newline (besides saving one byte in network transmissions), I think adding that newline at the appropriate place in the code is less work than actually reading my arguments :-)
