[PATCH] graph API: display uninteresting commits as '^' instead of '*'

[Adam Simpkins <simpkins@facebook.com>]

Using --graph and --show-all together now displays UNINTERESTING commits
using '^' characters instead of '*'.

Something like the following command will demonstrate the change:

   git log --graph --show-all ^HEAD~2 HEAD
