Subject: [PATCH 1/2] Documentation/fast-import: explain how to remove a note

From: Jonathan Nieder <[email-masked]>
Date: Tue, 1 Feb 2011 23:00:22 -0600

A notemodify (N) command with blob id consisting of 40 zeroes (so
is_null_sha1 is true) means to not add a note to replace the existing,
removed one.
