From c8af480f52b46e556d23ef012f3987aa3a0fc25b Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <calcurse@cryptocrack.de>
Date: Tue, 11 Jan 2011 22:10:48 +0000
Subject: Make parse_date accept several short forms.
Short forms are only accepted in interactive mode (e.g. when using the
"Go to" function, editing a recurrent item's end date, and so on).
Samples: "1/1/30" for "01/01/2030", "26" for the 26th of the currently
selected month/year or "3/1" for Mar 01 (or Jan 03, depending on the
date format) of the currently selected year.
