[tin-users] Headers view mode continuation character

[tin nua]

Hello list.

In article headers view mode(by hitting ^C-H),
when the header gets long the continuation character is \011,
I think it is a bit ugly.

I want to display it with the "+" character like in mutt/neomutt.
I want to change it to the "+" character,
but I can't find any config variable to change it.
Is it possible to change the display character from \011 to "+"?
