The use of the future is ambiguous, and since another patch will allow writing, I'd rather rephrase it as e.g.

Git currently does not write to this new configuration file.

I'd prefer having two separate patches for the config file and for the two others. If ignore and attributes are simple enough, they may go to the same patch, but ideally, there would be two separate patches again.

No doc for core.excludesfile and core.attributesfile change :-(.

The logic seems overly complex, and you duplicate the if() uselessly.

Why not just set the variable git_attributes_file before entering the if? Something like this:

diff --git a/attr.c b/attr.c
index 303751f..71dc472 100644
--- a/attr.c
+++ b/attr.c
@@ -515,6 +515,9 @@ static void bootstrap_attr_stack(void)

 	}

+		git_attributes_file = "foo";
+
 	if (git_attributes_file) {
 		elem = read_attr_from_file(git_attributes_file, 1);
 		if (elem) {

(obviously replacing "foo" by the actual code involving
home_config_paths(..., "attributes")).

Doing so, you may even get rid of the "if (git_attributes_file)" on the
next line.

Then, the logic is really "core.excludesfile defaults to the XDG file",
not "if such variable is set then do that else do something else".

Same remark here. Look at the patch I sent earlier to give a default
value:

http://thread.gmane.org/gmane.comp.version-control.git/133343/focus=133415

For example, you version reads from XDG file if core.excludesfile is
set, but the file it points to doesn't exist. I don't think this is
expected.

Err, why add and remove it? You just need to create it, right?

I don't like these relative references to $HOME. If you mean $HOME, why
not say

mkdir -p $HOME/.config/git/
echo "f attr_f" >$HOME/.config/git/

?

(you don't even need to "cd")
