        <pre>I am trying to use the clang-format-diff
(clang/tools/clang-format/clang-format-diff.py). In the current master version,
regex at line 68 of the file seems to capture the wrong filename. To elaborate,
this is an example output for `git diff -U0 HEAD^` command on my machine:


--- a/tmva/tmva/inc/TMVA/DNN/RNN/RNNLayer.h
+++ b/tmva/tmva/inc/TMVA/DNN/RNN/RNNLayer.h
@@ -29,2 +29,2 @@
-#ifndef TMVA_DNN_RNN_CELL
-#define TMVA_DNN_RNN_CELL
+#ifndef TMVA_DNN_RNN_LAYER
+#define TMVA_DNN_RNN_LAYER
@@ -55 +55 @@ template<typename Architecture_t>


On this output, the filename matcher is capturing filename as
b/tmva/tmva/inc/TMVA/DNN/RNN/RNNLayer.h while it should actually capture
tmva/tmva/inc/TMVA/DNN/RNN/RNNLayer.h</pre>
        </div>
