show: Convert text format to the new self-recursive style
This is all code movement and a smidgen of glue. This moves the existing text formatter code into one self-recursive function, but doesn't change any of the logic. The next patch will actually take advantage of what the new structure has to offer. Note that this patch retains format_headers_message_part_text because it is also used by the raw format.
