[PATCH 3/3] Add shortcut in refresh_cache_ent() for marked entries.

From: Marius Storm-Olsen <marius@trolltech.com>
Date: May 30, 2008, 12:38 UTC
Message-ID: <c581c03d8d8bfc76753018d4399a79b02a057186.1212152269.git.marius@trolltech.com>

When a cache entry has been marked as CE_VALID, the user has promised us that any change in the work tree does not matter. Just mark the entry as up-to-date, and continue.
