I believe the 5.07 parser (thanks David!) is suppose to handle this in
input.

I wouldn't say it is extensively tested.

If you do an "epdload" or a "set position" it doesn't yet add a FEN tag
to the list of tags, however it shouldn't be that difficult to add if
someone is minded to (anyone doing it would be well advised to add a
"show tags" command as well I think, for debugging if nothing else).

I'll add it to the "TODO" list, but that doesn't mean I have time to do
it alas. (Oops "Board is wrong" bug discovered whilst looking at this- grr).

Currently this is about your lot.....
