If I'm reading

https://tools.ietf.org/html/rfc2646

right, that's not how this is supposed to work, and `fill-flowed' does
it correctly -- it's supposed to flow together lines that have the same
quotation level, like this:

(with-temp-buffer
  (require 'flow-fill)
  (insert " > ABC \n> DEF\n")
  (fill-flowed)
  (buffer-string))
