The list flattening operator is ^ not " in the unix rc. i.e. echo $^t

This is mentioned in the INCOMPATIBILITIES section of the manpage.
Don't know why this is the case, other than to avoid possible confusion
with the meaning of " as a quote char in other unix shells, plus ^ is
used as the concatenation operator anyway as in:
; echo (a b c)^(1 2 3)
