That's true.   However, this reminded me that we do have pretty good
completion in `M-!', so I thought we must have some tokenisation support
somewhere, and indeed: `shell--parse-pcomplete-arguments' seems to fit
the bill here.  So adding a `shell-split-string' by wrapping that
function seems like it should be possible.  I'll poke some more at it;
it doesn't quite seem to handle \ as expected in all circumstances.

It handles "" and '' fine, as far as I can tell:

'foo"bar' zot
-> (("foo\"bar" "zot") 1 11)
