Expand code diffs against the commits repo

Browse source 
When expanding code diffs, the expansion should search for more context
in the commits repo, rather than in the repo in context, because the
commit may not be available in the base repo. For example, when
previewing a pull request, the commit is not in the target repo yet -
it's in the fork.

Fixes #3746.
