Thanks, that fixed it! I do still think it's pretty strange, though,
because select-a-shell-word does not normally seem to respond to the
numeric argument in a command like `v3aa` (still only selects one
word).

Nice, thanks for pointing that out.

I want to select the nth argument on the command line, taking into
account spaces, so using vi-forward-word is not a good choice. For
example, on the command `echo "these are all one" third` I want
3:select-n-shell-word to select

echo "these are all one"[ third]

not

echo[ "these are all one"] third

Oops, thank you for that as well.

I appreciate all the help! It's working perfectly now.
