	* sem_warn.adb (Is_OK_Fully_Initialized): Consider types with DIC as
	fully default initialized.
	* sem_ch6.adb: minor style fix in comment

2015-10-20  Ed Schonberg  <schonberg@adacore.com>

	* s-diflio.ads, s-diflio.adb (Image): New function for dimensioned
	quantities, to produce a string that includes the dimension
	synbol for the quantity, or the vector of dimensions in standard
	notation.
	* sem_dim.adb (Expand_Put_Call_With_Symbol): Process new function
	Image, to include dimension information in the generated string,
	identical to the string produced by the Put procedure on a string
	for a dimensioned quantity.
