check if userRName is already set

This probably should be revised to work if selection is in the message header rather than the message body.


[viewer: ViewerClasses.Viewer, event: ViewerEvents.ViewerEvent, before: BOOL] RETURNS[abort: BOOL _ FALSE]
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
this needs to be done first, before the user can change the selection out from under me ...
the "right" way would be to access the sending viewer later and make tioga lower level
calls, but CopyMessages is easier to use, so I just call it before the selection can change.
NOTE, however that if the message has troubles being sent, this copy will still work ...
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
now we are positioned at the beginning of the body of the message
if any recipient is at another arpa site, all recipients should be arpa qualified
however, like Laurel, we'll only do the From/Sender field in full arpa regalia
