Allow graph lines to jump through hyperspace.
When the graph gets too wide (as defined by the maxwidth variable, which can be set in ~/.gitk), we can now terminate graph lines with an arrow pointing downwards, and reintroduce them later with an arrow pointing upwards when we need them. This makes the graph much less cluttered on large repositories such as the linux kernel. Unfortunately this has made it slower; it takes about 10 seconds user time on the linux-2.6 repository on my machine now, compared to 6 seconds before. I'll have to work on optimizing that. Also on the todo list are making the arrow heads active (so if you click on them you jump to the other end) and improving the placement of the null entry.
