Add support for value subscript after expansionsadhoc-recipe-history
Value subscript is only recognized in evaluation contexts (due to ambiguity
with wildcard patterns; consider: $x[123].txt) and should be unseparated from
the previous token. For example:
x = ($y[1])
x = (($f ? $y : $z)[1])
x = ($identity($x)[$z])
