Forward operations are virtually the same, except for a few email header differences.
All of this busy-ness comes “for free,” because Reply and Forward pages are generated
by calling commonhtml.editpage, the same utility used to create a new mail composition

add “Re:” to the subject text). We applied the same sort of reuse trick in PyMailGUI,
but in a different context. In PyMailCGI, one script handles three pages; in PyMailGUI,
one superclass and callback method handles three buttons, but the architecture is sim-
ilar in spirit.
