Literal sub-numbering of unpublished items

[art-keidan]

One more useful feature to implement would be the literal numbering of the unpublished items. For example, if there are two, or more, publications indicated as Forthcoming, they should be labeled as Forthcoming a, Forthcoming b, etc. As for now, all the forthcoming (or other unpublished) items repeat the same label with no differentiation, which is a bit redundant (see the example below).

Please try this:

% Add extra label also to pubstate, and prefer pubstate over year.
\renewbibmacro*{bpl:date:makedate}{%
  \printtext{%
     \iffieldundef{pubstate}{%
        \iffieldundef{year}{}{%
          \printfield{labelyear}%
          \printfield{extradate}%
        }%
      }{%
       \printfield{pubstate}%
       \printfield{extrayear}%
      }%
     }%
}

Thanks, it works.

Next version (1.22) will have an option pubstateextra where you can switch this on.
