K&R (second edition, of course) section A8.7 says:

  The initializer is preceded by =, and is either an expression, or a
  list of initializers nested in braces.  A list may end with a comma,
  a nicety for neat formatting.

It seems to be talking about a general enough context to include
arrays and structs, though it's not _entirely_ clear to me; the second
example on the top of p. 220 is an array with an extra comma at the
end.
