[PATCH 07/14] range-diff: respect diff_option.file rather than assuming 'stdout'

Message-ID: <20180722095717.17912-8-sunshine@sunshineco.com>

The actual diffs output by range-diff respect diff_option.file, which range-diff passes down the call-chain, thus are destination-agnostic. However, output_pair_header() is hard-coded to emit to 'stdout'. Fix this by making output_pair_header() respect diff_option.file, as well.
