"a.matrix[a.char.matrix]<- " crashes R (PR#447)

I think that is the correct behaviour. (What is the expected behaviour? It is what I expected.) A k-index (aka matrix or array subset) is supposed to give the indices of the elements to be extracted/replaced. I suppose character values could be matched to dimnames, but that would be a new idea.
...but what the user most likely expected! We might want to *warn*. Right.
On the other hand, S-PLUS's print routine seems to ignore the added elements, and R loses the dim attribute.
As usual when length and dims develops a mismatch... R is saner, I think
repeated *new *indices. The hackery in StringSubscript was copying the wrong string as a name for duplicate string indices. Fixed.
So did I but not correctly (had indexnames instead of s). Thanks.
