This patch modifies the behavior of Getopt in GNAT.Command_Line to not call
the Callback function in argument on switches that have been dealt with
automatically.

Tested on x86_64-pc-linux-gnu, committed on trunk

2011-09-02  Johannes Kanig  <kanig@adacore.com>

	* g-comlin.adb (Getopt): Return when switch is dealt with automatically,
	instead of calling the callback function
