git-gui waits to color until after it gets the move/copy annotations
back from the -C -C -w second pass it does.  This way the coloring
is based on the original source location, not on the move/copy that
caused it to be placed where it is now.

I played around with this for a while and finally made it work the
way it does as I assumed most users would want to see where something
originally came from more than how it got moved to where it is now.

IOW the (very expensive) -C -C -w pass is usually much more
interesting than the default (fast) pass, so that is the line
annotation data we color with.  But it takes longer to get and
is run second, so yea, coloring takes a while.
