Fix pretty printing of pointer_diff node

While working on un-sharing diff nodes, I observed that the pretty
printed representation of pointer_diff nodes  was lacking an opening
square bracket.  Fixed thus.

	* src/abg-comparison.cc (pointer_diff::get_pretty_representation):
	Add the missing opening square bracket.
