diff: simplify color_moved check when flushing

In diff_flush_patch_all_file_pairs(), we set o->emitted_symbols if and only if o->color_moved is true. That causes the lower-level routines to fill up o->emitted_symbols, which we then analyze in order to do the actual colorizing. But in that final step, we do: if (o->emitted_symbols) { if (o->color_moved) { ...actual coloring... } ...clean up of emitted_symbols... } The inner "if" will always trigger, since we set emitted_symbols only when doing color_moved (it is a little confusing that it is set inside the diff_options struct, but that is for convenience of passing it to the lower-level routines; we always clear it at the end of flushing, since 48edf3a02a (diff: clear emitted_symbols flag after use, 2019-01-24)). Let's simplify the code a bit by just dropping the inner "if" and running its block unconditionally. In theory the current code might be useful if another feature besides color_moved setup and used emitted_symbols, but it would be easy to refactor later to handle that. And in the meantime, this makes further work in this area easier. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
