Nit: put spaces around '+'

Done.

In anticipation of possible questions: there are two ways to achieve this
result: either complicate val_runner to support golden files (in this case
val_runner, annotate_tf and hex2tf will be slightly more indirect), or keep
common usage simple and use somewhat ugly monkeypatching only in hex2tf. Given
that hex2tf is a throw-away, I chose second approach.

+    def MonkeyRunner(hex_name):
+      # hex_name passed here is the name of temporary hex file,
+      # so to obtain path to gold we use hex_path instead.
+      golden_ext = {32: '.nval', 64: '.rval'}[options.bits]
+      golden_path = os.path.splitext(hex_path)[0]+golden_ext
+      with open(golden_path) as fin:
+        return fin.readlines()
+
+    if options.bits == 32:
+      backup_runner = val_runner.RunNcVal32
+      val_runner.RunNcVal32 = MonkeyRunner
+    elif options.bits == 64:
+      backup_runner = val_runner.RunNcVal64
+      val_runner.RunNcVal64 = MonkeyRunner
+
+    try:
+      annotated_lines = annotate_tf.Annotate(['nc'], original_lines)
+    finally:
+      if options.bits == 32:
+        val_runner.RunNcVal32 = backup_runner
+      elif options.bits == 64:
+        val_runner.RunNcVal64 = backup_runner
+
+    with open(tf_path, 'w') as fout:
