Well, we (i.e., Peter and Martyn) have found *why* it happens.
However, this is a semantic change from older versions of R and from S
which I consider serious [a bug ?!?] an we should discuss.
This wasn't a deliberate change, just my usual incompetence. I think it crept in when we changed c() to be a generic function (which does method dispatch internally). The problem is in the function "ExtractOptionals" in bind.c. There the matching of arguments is done in two places with pmatch using a third argument which is 0. This indicates partial matching and should be changed so that the third argument is 1 indicating exact matching.
