From 2fe7a36aab8c6c934550b2b8dc2074c1af23859a Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <calcurse@cryptocrack.de>
Date: Tue, 2 Aug 2011 21:42:10 +0200
Subject: Accept variable length note names

Read up to the first blank in note_read() instead of assuming a
fixed-width note file name. Accept everything up to 40 characters (which
is the length of a SHA1 hash in hexadecimal representation).
