Ah, I misremembered.  Your current patch shows this:

+       else if (actions & ACTION_EDIT) {
+               const char *config_filename;
+               if (config_exclusive_filename)
+                       config_filename = config_exclusive_filename;
+               else
+                       config_filename = git_path("config");
+               git_config(git_default_config, NULL);
+               launch_editor(config_filename, NULL, NULL);
+       }

... which makes me believe that the point about moving git_config() before 
setting config_exclusive_filename is rather weak :-)

+       else if (actions & ACTION_EDIT) {
+               git_config(git_default_config, NULL);
+               launch_editor(config_exclusive_filename ?
+			config_exclusive_filename : git_path("config"), 
+			NULL, NULL);
+       }

(This has whitespace issues, as I copy-pasted it using kterm's clipboard 
functions.)

Ciao,
Dscho
