[PATCH 12/25] diff.c: emit_diff_symbol learns DIFF_SYMBOL_HEADER

From
Stefan Beller <sbeller@google.com>
Date
Jun 30, 2017, 00:06 UTC
Message-ID
<20170630000710.10601-13-sbeller@google.com>
In-Reply-To
<20170630000710.10601-1-sbeller@google.com>

The header is constructed lazily including line breaks, so just emit the raw string as is.
