Joseph's comments on patch 2 in the series prompted me to change
how the array (and VLA) function parameters are formatted: instead
of implementing it mostly outside the pretty printer (which, to do
completely correctly, would require reimplementing what the pretty
printer already does) I instead enhanced the pretty printer.  That
let me simplify the formatting done in the helper.  The attached
revision reflects this simplification (the only change from
the original is to attr_access::array_as_string).
