The followig should do it as long as person_wifehusbandname is actually a
zero-length string, not a set of spaces:
{ MERGEFIELD personname }{ IF "{ MERGEFIELD person_wifehusbandname }" = ""
"" " & { MERGEFIELD person_wifehusbandname }" }
All the pairs of {} need to be the special field code braces that you can
insert using ctrl-F9. Everything is ordinary text that you can type on the
keyboard. The whole thing can be on a single line.
