auto-wrap in editor<%>

Enables or disables automatically calling set-max-width in response to on-display-size, or gets the state of auto-wrapping. For text editors, this has the effect of wrapping the editor's contents to fit in a canvas displaying the editor (the widest one if multiple canvases display the editor). For pasteboard editors, ``auto-wrapping'' merely truncates the area of the pasteboard to match its canvas display.

Auto-wrapping is initially disabled.

• (send an-editor auto-wrap auto-wrap?) -> void
     auto-wrap? : boolean
