+Subject: [PATCH] sed: fix symlink bufsize readlink check
+
+Problem reported by Hauke Mehrtens.
+* sed/utils.c (follow_symlink): Fix typo when checking size of
+second and later symlink, when that symlink is so large that it
+does not fit into the buffer.  Although the bug is not a buffer
+overflow, it does cause sed to mishandle the symlink.
+* testsuite/follow-symlinks.sh: Test for the bug.
