[PATCH 1/5] parse-options.c: introduce OPT_DATE

[Junio C Hamano <junio@xxxxxxxxx>]

From: Michele Ballabio <barra_cuda@xxxxxxxxxxxx>
Date: Mon, 24 Mar 2008 15:02:21 +0100

There are quite a few places that will need to call approxidate(),
when they'll adopt the parse-options system, so this patch adds the
function parse_opt_approxidate_cb(), used by OPT_DATE.
