[PATCH] file_exists(): dangling symlinks do exist

From: Junio C Hamano <gitster@pobox.com>
Date: Nov 18, 2007, 10:21 UTC
Message-ID: <1195381287-26823-1-git-send-email-gitster@pobox.com>

This function is used to see if a path given by the user does exist on the filesystem. A symbolic link that does not point anywhere does exist but running stat() on it would yield an error, and it incorrectly said it does not exist.
