From a392f57daf7dc5e72ab3ada7802eddc000fa3081 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 13 Jan 2016 16:14:48 -0800 Subject: [PATCH] checkout-index: there are only two possible line terminations The program by default reads LF terminated lines, with an option to use NUL terminated records. Instead of pretending that there can be other useful values for line_termination, use a boolean variable, nul_term_line, to tell if NUL terminated records are used, and switch between strbuf_getline_{lf,nul} based on it.
