Subject: gitview: Display the lines joining commit nodes clearly.
X-Git-Tag: v1.3.0-rc1~153^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3fe5489a2550118e0eb3f90e348cb78afeeb61e0;p=git.git

gitview: Display the lines joining commit nodes clearly.

Since i wanted to limit the graph box size i was resetting
the window after an index of 5. This result in line joining
commit nodes to pass over nodes which are not related. The
changes fixes the same
