The whitespace changes were done with these commands on RHEL7 (sed's -c preserves file permissions and ownership).

export LC_CTYPE=C
export LANG=C

# Remove trailing whitespace
find . -not \( -name .svn -prune -o -name .git -prune \) \( -iname "*.php" -o -iname "*.txt" -o -iname "*.xml" \) -type f -print0 | xargs -0 sed -c -i -E "s/[[:space:]]*$//"

# Combine multiple trailing newlines at EOF
find . -not \( -name .svn -prune -o -name .git -prune \) \( -iname "*.php" -o -iname "*.txt" -o -iname "*.xml" \) -type f -print0 | xargs -0 sed -c -i -e :a -e '/^\n*$/{$d;N;};/\n$/ba'

# Add a trailing newline if there is not one
find . -not \( -name .svn -prune -o -name .git -prune \) \( -iname "*.php" -o -iname "*.txt" -o -iname "*.xml" \) -type f -print0 | xargs -0 sed -c -i -e '$a\'

The php ending tags were removed after that manually (which explains why a few files were missed).
