From f192223447746a503bf664135a0e537d15876ebe Mon Sep 17 00:00:00 2001 From: John Keeping Date: Thu, 7 Feb 2013 20:15:26 +0000 Subject: diff: add diff_line_prefix function This is a helper function to call the diff output_prefix function and return its value as a C string, allowing us to greatly simplify everywhere that needs to get the output prefix.
