From fa325e9b42b0bdfb48857d1958d9fb7ceac55151 Mon Sep 17 00:00:00 2001
From: Dan Cross <cross@gajendra.net>
Date: Fri, 10 Jan 2020 14:44:21 +0000
Subject: Trivial changes: whitespace and modes.

Remote whitespace at the ends of lines.
Remove blank lines from the ends of files.
Change modes on source files so that they
are not executable.

Signed-off-by: Dan Cross <cross@gajendra.net>
