Subject: Work around what appears to be a flex bug when dealing with files
X-Git-Tag: SUDO_1_6_7~92

Work around what appears to be a flex bug when dealing with files
that lack a final newline before EOF.  This adds a rule to match
EOF in the non-initial states which resets the state to INITIAL and
throws an error.
