I'm not so sure about that.  With your example I get this diff without
setting diff.natvis.xfuncname:

diff --git a/a.natvis b/a.natvis
index 7f9bdf5..bc3c090 100644
--- a/a.natvis
+++ b/a.natvis
@@ -19,7 +19,7 @@ xmlns="http://schemas.microsoft.com/vstudio/debugger/natvis/2010">
 
 
       <!-- Non-blank line -->
-      <Item Name="added var">added_var</Item>
+      <Item Name="added var">added_vars</Item>
 
 
       <Item Name="var2">var2</Item>

Note the XML namespace in the hunk header.  It's put there by the
default rule because "xmlns" starts at the beginning of the line.  Your
diff has nothing there, which means the default rule is not used, i.e.
your user-defined rule is in effect.

Come to think of it, this line break in the middle of the AutoVisualizer
tab might have been added by your email client unintentionally, so that
we use different test files, which then of course results in different
diffs.  Is that the case?

Anyway, if I run the following two commands:

$ git config diff.natvis.xfuncname "^[\t ]*<Type[\t ]+Name=\"([^\"]+)\".*$"
$ echo '*.natvis diff=natvis' >.gitattributes

... then I get this, both on Linux (git version 2.11.1) and on Windows
(git version 2.11.1.windows.1):

diff --git a/a.natvis b/a.natvis
index 7f9bdf5..bc3c090 100644

At this point I'm out of ideas, sorry. :(  The only way I was able to
break it was due to mistyping the extension as "netvis" several times
for some reason.
