[PATCH 2/2] strbuf_add_commented_lines(): drop the comment_line_char parameter

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

All the callers of this function supply the global variable
comment_line_char as an argument to its last parameter.  Remove the
parameter to allow us in the future to change the reference to the
global variable with something else, like a function call.
