git-mv: fully detect 'directory moved into itself'

From: Josef Weidendorfer <josef.weidendorfer@gmx.de>

Message-ID: <200511272206.43113.Josef.Weidendorfer@gmx.de>

This gives a better error message when trying to move a directory into some subdirectory of itself; ie. no real bug fix: renaming already failed before, but with a strange "invalid argument".
