Message:

Build reply commands from scratch on outgoing zwrites

We currently reuse the original zwrite line which is problematic when
the user passed -m. Instead regenerates the zwrite line from the
parsed owl_zwrite.

Repurpose the zwriteline attribute because anyone using the old
attribute probably has the same bug.
