format-patch: generate MIME header as needed even when there is format.header
Earlier, the callchain from pretty_print_commit() down to pp_title_line() had an unwarranted assumption that the presense of "after_subject" parameter, means the caller has already output MIME headers for attachments. The parameter's primary purpose is to give extra header lines the caller wants to place after pp_title_line() generates the "Subject: " line. This assumption does not hold when the user used the format.header configuration variable to pass extra headers, and caused a message with non-ASCII character to lack proper MIME headers (e.g. 8-bit CTE header). The earlier logic also failed to suppress duplicated MIME headers when "format-patch -s --attach" is asked for and the signer's name demanded 8-bit clean transport. This patch fixes the logic by introducing a separate need_8bit_cte parameter passed down the callchain. This can have one of these values: -1 : we've already done MIME crap and we do not want to add extra header to say this is 8bit in pp_title_line(); 0 : we haven't done MIME and we have not seen anything that is 8bit yet; 1 : we haven't done MIME and we have seen something that is 8bit; pp_title_line() must add MIME header. It adds two tests by Jeff King who independently diagnosed this issue. Signed-off-by: Junio C Hamano <>
