Re: [PATCH] gitattributes: Cover Objective-C source files

[Akihiko Odaki <akihiko.odaki@gmail.com>]

I don't think this is needed. I could see a diff annotated with a method 
name even without this change:
% git diff
diff --git a/ui/cocoa.m b/ui/cocoa.m
index cb6e7c41dc6..14a4416cc8b 100644
--- a/ui/cocoa.m
+++ b/ui/cocoa.m
@@ -1264,6 +1264,7 @@ - (id) init
          [pauseLabel setTextColor: [NSColor blackColor]];
          [pauseLabel sizeToFit];
      }
+    //
      return self;
  }

Commit 29cf16db23 says:

So I suspect Git has some knowledge of common file extensions like .c, 
.h and .m although I couldn't find in the source code of Git.
