Re: [RFC PATCH 2/3] strbuf_commented_addf(): drop the comment_line_char parameter

> From: Junio C Hamano <gitster@pobox.com>
>
> All the callers of this function supply the global variable
> comment_line_char as an argument to its second 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.
