[PATCH 1/2] commit-graph: create local repository pointer

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

The write_commit_graph() method uses 'the_repository' in a few places. A
new need for a repository pointer is coming in the following change, so
group these instances into a local variable 'r' that could eventually
become part of the method signature, if so desired.
