Fix EOL at EOF

Commands used to search and replace:

    $ git grep -Ilz '.' | xargs -0 -I '{}' sh -c \
      "printf '%s\n' \"\$(cat '{}')\" >'{}'"

The above commands ensure that there is exaclty 1 line terminator at EOF
(rather than 0 or more than 1) on all non-empty text files.

This fixes all of the "new blank line at EOF" errors raised by git:

    $ git diff --check 4b825dc642cb6eb9a060e54bf8d69288fbee4904..HEAD |
      grep '^[^+]' | cut -f 3 -d : | LC_ALL=C sort | uniq -c
         21  new blank line at EOF.
         72  space before tab in indent.
          4  trailing whitespace.
