Fix out of range regression -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Fix out of range regression From: Filip Brcic <brcha@users.sourceforge.net> The old revlog.py issued "index out of range" error when cloning the repository Now I have reverted the parts of revlog.py to the old state when prev was initialized as -1 and later assigned self.tip() only if that is possible. Previously prev was always initialized as self.tip() and that is where the out of range error was. manifest hash: c94c9aee8b6d382ef52c3981f306a6e7e5f4c4d1 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCzzIxywK+sNU5EO8RAtlcAJ0TX9FXuC2c3YHuYXNwqZhdzPWUlgCggq+a yJzUKDKH/gvnD3Tx3jcmCn8= =euPi -----END PGP SIGNATURE-----
