combine-diff: move formatting logic to show_combined_diff()
This way, diff-files can make use of it. Also implement the full suite of what diff_flush_raw() supports just for consistency. With this, 'diff-tree -c -r --name-status' would show what is expected. There is no way to get the historical output (useful for debugging and low-level Plumbing work) anymore, so tentatively it makes '-m' to mean "do not combine and show individual diffs with parents". diff-files matches diff-tree to produce raw output for -c. For textual combined diff, use -p -c. Signed-off-by: Junio C Hamano <junkio@cox.net>
