d5e44d84	2012-11-29T17:02:27	Fix function name and add real error check `revwalk.h:commit_lookup()` -> `git_revwalk__commit_lookup()` and make `git_commit_list_parse()` do real error checking that the item in the list is an actual commit object. Also fixed an apparent typo in a test name.

0984c876	2012-11-28T18:27:43	Rename git_count_ahead_behind -> git_graph_ahead_behind Moved it into graph.{c,h} which i created for the new "graph" functions namespace. Also adjusted the function prototype to use `size_t` and `const git_oid *`.
