Re: Trying to use xfuncname without success.

So, to make sure we are on the same page, I removed the
diff.natvis.xfuncname from the .gitconfig and .git/config.  My output
was:

C:\Users\adrianh\Documents\tmp>git diff
diff --git a/test.natvis b/test.natvis
index 93fd5b4..351301f 100644
--- a/test.natvis
+++ b/test.natvis
@@ -18,6 +18,7 @@


          <!-- test text -->
+         <Item Name="added var">added_var</Item>


       <Item Name="var2">var2</Item>

So I didn't get the default output that your specified.

I've been modifying the .gitconfig file directly, but I tried your command:

git config diff.natvis.xfuncname "^[\t ]*<Type[\t ]+Name=\"([^\"]+)\".*$"

and still had the same results.  I.e. NOTHING. :(
