Hi Stefan,

If you need to re-roll your 'sb/diff-color-move' branch, could you
please squash this into to the relevant patches. (Each hunk would
be squashed into a separate commit, thus:
  - commit 9b68d54c11, "diff: buffer all output if asked to"
  - commit 4b71ba47ab, "submodule.c: convert show_submodule_summary to use emit_line_fmt"
  - commit 703d25581d, "diff.c: convert show_stats to use emit_line_*"
).

Thanks!

ATB,
Ramsay Jones
