[PATCH v4 06/21] check-ignore: there are only two possible line terminations

[Junio C Hamano <gitster@pobox.com>]

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.
