    graph: add support for --line-prefix on all graph-aware output · 660e113c
    Jacob Keller authored
    Add an extension to git-diff and git-log (and any other graph-aware
    displayable output) such that "--line-prefix=<string>" will print the
    additional line-prefix on every line of output.
    To make this work, we have to fix a few bugs in the graph API that force
    graph_show_commit_msg to be used only when you have a valid graph.
    Additionally, we extend the default_diff_output_prefix handler to work
    even when no graph is enabled.
    This is somewhat of a hack on top of the graph API, but I think it
    should be acceptable here.
    This will be used by a future extension of submodule display which
    displays the submodule diff as the actual diff between the pre and post
    commit in the submodule project.
    Add some tests for both git-log and git-diff to ensure that the prefix
    is honored correctly.
