From 7fb0eaa289576a1dcd7751015ba791f1bce778a9 Mon Sep 17 00:00:00 2001
From: Junio C Hamano <gitster@pobox.com>

Subject: [PATCH] git_attr(): fix function signature

The function took (name, namelen) as its arguments, but all the public
callers wanted to pass a full string.

Demote the counted-string interface to an internal API status, and allow
public callers to just pass the string to the function.
