Thread:Manual talk:Coding conventions/Trailing whitespace/reply (4)

The convention was added in this edit. It was expanded a bit in subsequent edits by Nemo and others.

The current language is pretty stupid, in my opinion. I think it gives the impression that a trailing newline in a file is a bad thing, which is obviously not true, and it provides an overbearing "don't do this" without providing any rationale for why this is problematic.
