+Partially fix CVE-2014-9112, part 5/5. Backported to 2.11.

+Subject: Fix symlink-bad-length test for 64-bit architectures.
+
+* src/util.c: Return non-zero exit code if EOF is hit prematurely.
+* tests/symlink-bad-length.at: Revert to original archive: there's
+no use testing for recovery, because that depends on the host
+architecture. Don't test for exit code as well (same reason).
+Account for eventual warning messages.
