Dash is considered a character that needs quoting.  It might be possible
to avoid that if we could be certain that appendShellString's output would
never be placed in a spot where it could be taken for a switch, but that
seems like a large assumption to me.  Or maybe we could treat it as
forcing quotes only if it starts the string; but I don't personally care
enough to write the code for that.  Feel free if you want to.

Hmm, not intentional ... [ looks closely... ]  Looks like a tab got in
there somehow.  Will fix.

I think that's intentional, not accidental.  What actual use case is
there for allowing such paths?
