A shorter version is
> x <- 1:9; x[-c(-1,NA,3:5)]
Error: only 0's may mix with negative subscripts
which used to simply give
> x <- 1:9; x[-c(1,NA,3:5)]
[1] 2 6 7 8 9
and is the same if there was no NA in the index -- without a warning;
not necessarily desirable as well.

However, the current NEWS file does say
o Negative subscripts that were out of range or NA were not handled
correctly.
R 1.9.0 (beta)'s behavior seems to match the one of S-plus here,
but that alone is not convincing enough IMO.
