Subject: [PATCH v3 1/4] t0060: Add test for manipulating symlinks via absolute paths

From: Martin Erik Werner <[email-masked]>
Date: Fri, 31 Jan 2014 21:22:01 +0100

When symlinks in the working tree are manipulated using the absolute
path, git dereferences them, and tries to manipulate the link target
instead.

This is a regression introduced by 18e051a:
  setup: translate symlinks in filename when using absolute paths
(which did not take symlinks in the work tree into consideration).

Add a known-breakage tests using the prefix_path function, which
currently uses real_path, causing the dereference.
