Use the after_subject member of struct pretty_print_context to pass the
extra_headers unchanged, and construct and add the MIME boundary headers
directly in pretty.c::pp_title_line() instead of writing both to a
static buffer in log-tree.c::log_write_email_headers() first. That's
easier, quicker and gets rid of said static buffer.
