	* sem_ch10.adb, atree.adb: Minor reformatting.

2015-11-12  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_elab.adb (Check_A_Call): Add new variable
	Is_DIC_Proc. Report elaboration issue in SPARK concerning calls
	to source subprograms or nontrivial Default_Initial_Condition
	procedures. Add specialized error message to avoid outputting
	the internal name of the Default_Initial_Condition procedure.
	* sem_util.ads, sem_util.adb
	(Is_Non_Trivial_Default_Init_Cond_Procedure): New routine.
