Subject: [PATCH 1/2] gitview: Fix the blame interface.

From: "Aneesh Kumar K.V" <[email-masked]>
Date: Wed, 13 Jun 2007 14:16:15 +0530

The async reading from the pipe was skipping some of the
input lines. Fix the same by making sure that we add the
partial content of the previous read to the newly read
data.
