still resolve to that stream.  See Changelog mod from this commit for
details.

+	* Bug fix: properly handle overridden compressed objects.  When
+	caching objects from an object stream, only cache objects that,
+	based on the xref table, would actually be resolved into this
+	stream.  Prior to this fix, if an object stream A contained an
+	object B that was overridden by an appended section of the file,
+	qpdf would cache the old value of B if any non-overridden member
+	of A was accessed before B.  This commit fixes that bug.
