for example

argu e edit -- -e -> single blank line
argu a append -- -a -> '-a'
argu a append -- --append -> '--append'
argu e edit -- --edit -> --edit

By reading the source of argu, I suspect you are running into a problem with echo. To demonstrate

echo -E '-e' -> blank line
echo -E '-E' -> blank line
echo -E '-s' -> blank line
echo -E '-n' -> blank line
echo -E '-q' -> '-q'

So echo is eating any options that it itself uses.

The appropriate fix is probably to use printf "%s\n" "$argv[1]" (and so on) instead of echo -E "$argv[1]", since printf has no options

Let me know if you think this bug should also be filed upstream; I'm currently undecided on that.
