format-patch: wrap long header lines
Subject and identity headers may be arbitrarily long. In the past, we just assumed that single-line headers would be reasonably short. For multi-line subjects that we squish into a single line, we just "pre-folded" the data in pp_title_line by adding a newline and indentation. There were two problems. One is that, although rare, single-line messages can actually be longer than the recommended line-length limits. The second is that the pre-folding interacted badly with rfc2047 encoding, leading to malformed headers. Instead, let's stop pre-folding the subject lines, and just fold everything based on length in add_rfc2047, whether it is encoded or not.
