It sounds like your shell is confused, either by this line (line 15):
NULLCMD=:
or by this one (line 16):
elif test -n "${BASH_VERSION+set}" && (set -o posix) >/dev/null 2>&1; then
What shell are you using? What operating system are you running it on?
What happens when you try to run this command with your shell?
NULLCMD=:
What happens when you try to run this command?
if false; then
echo 1
elif true; then
echo 2
fi
