Subject: [PATCHv3 02/20] diff: move line ending check into emit_hunk_header
Date: Thu, 18 May 2017 12:37:28 -0700	[thread overview]
Message-ID: <20170518193746.486-3-sbeller@google.com> (raw)
In-Reply-To: <20170518193746.486-1-sbeller@google.com>

The emit_hunk_header() function is responsible for assembling a
hunk header and calling emit_line() to send the hunk header
to the output file.  Its only caller fn_out_consume() needs
to prepare for a case where the function emits an incomplete
line and add the terminating LF.

Instead make sure emit_hunk_header() to always send a
completed line to emit_line().
