cbrob() with long argument list

[RobinHankin]

Leo Gürtler points out that there is an infelicity in cbrob():

> a <- lapply(seq_len(10), function(x) as.brob(x))
> ignore <- do.call("cbrob",a)
> 
> 
> a <- lapply(seq_len(1000), function(x) as.brob(x))
> ignore <- do.call("cbrob",a)
Error: C stack usage  9522308 is too close to the limit
> 

I don't think this is a bug as such but it should be documented.

It is possible to use the accessor methods and build a brob directly:

> a <- lapply(seq_len(1000), function(x) as.brob(x))
> ignore <- brob(unlist(lapply(a,getX)),unlist(lapply(a,getP)))
>

Both observations above should appear in the documentation somewhere.
