I am unable to find anything in Harbison and Steele which indicates
that a trailing comma is acceptable in an array initializer.  (They
don't seem to mention it one way or another.)

I recall using some compilers in the past where a trailing comma in an
array initializer was definitely not accepted.  In fact, I was told at
the time that some code I had written which had a trailing comma was
not standards compliant.
