Seems like it's not been implemented.

In FormFieldChoice::FormFieldChoice (poppler/Form.cc), editedChoice is 
initially assigned NULL and never changed.
I think it should be given the value in /V if /V is a string and doesn't match 
any of the predefined choices. Note that the piece of code that parses /V is 
one of the things that I'm working on (thread: "Patches for form choice 
fields").

By the way, I noticed that FormFieldChoice::setEditChoice internally calls 
unselectAll to deselect predefined options. Maybe select/selectAll/etc.. 
should similarly set editedChoice to NULL?
