[PATCH 2/3] truncate cwd string before printing error message

From: Lars R. Damerow <lars@pixar.com>

Message-ID: <1268855753-25840-3-git-send-email-lars@pixar.com>
In-Reply-To: <1268855753-25840-1-git-send-email-lars@pixar.com>

Without this truncation the error message printed only shows the cwd from the start of the search, not where it failed.
