This seems to be deliberate, since paste.c says
if(maxlen == 0)
return mkString("");
but it is not documented and it is not what S (even S+3.4) does.
On the other hand, S gives
> paste(character(0), character(0), collapse="+")
[1] " "
which looks incorrect to me (and R gives "" which I reckon to be right).
Anyone know the rhyme or reason here?
