	* libgimpbase/gimputils.[ch] (gimp_memsize_to_string): take a
	guint64 parameter and handle values beyond a gigabyte.

	* app/core/gimptemplate.[ch]: use a guint64 for the initial memory
	size and removed the gboolean that used to indicate a gulong
	overflow.

	* app/widgets/gimptemplateeditor.[ch]: changed accordingly.

	* app/gui/file-new-dialog.c: don't set the OK button insensitive
	when the initial memory size exceeds GULONG_MAX.

	* app/widgets/gimpsessioninfo.c (gimp_session_info_deserialize):
	replaced a misleading comment.
