It seems the extraction process was rototiles several times within the
last few weeks, and i think this just fell through the cracks - i've fixed
this now, thanks. 

For your question, the "canonical" way to extract several files is to set
EXTRACT_ONLY (which defaults to all distfiles). If you want a special
extraction command, put it in EXTRACT_CMD, and refer to the (single)
distfile to be extracted (in this look's run) with ${DOWNLOADED_DISTFILE}.
If you need only some files extracted from a tar- or whatever archive, set
EXTRACT_ELEMENTS (defaulting to all).

Returning to your original question, setting WRKSRC to anything like
EXTRACT_ELEMENTS (or similar the old EXTRACT_AFTER_ARGS), this only works
if you have one element to extract, of course.

I hope this helps a bit.
