R devel - Nov 1998 - list assignment

There appears to be a problem with name matching in list assignment:

Version 0.63.0  (November 14, 1998)
...
> r <- list()
> r$forecast.cov.trend <- 1:12
> r$forecast.cov.zero <- 1:12
> r$forecast.cov <- 1:2
> length(r$forecast.cov)
[1] 0                                   #should be 2
>
But note that this works correctly:
>  r <- list()
> r$forecast.cov.trend <- 1:12
> r$forecast.cov <- 1:2
> length(r$forecast.cov)
[1] 2
>
And also this works correctly:
> r <- list()
> r$forecast.cov <- 1:2
> r$forecast.cov.trend <- 1:12
> r$forecast.cov.zero <- 1:12
> length(r$forecast.cov)
[1] 2
> length(r$forecast.cov.trend)
[1] 12
> length(r$forecast.cov.zero)
[1] 12

Odd, and clearly a bug. Probably rather in indexing rather than
assigment, though:
> a<-list(1,2,3)
> names(a)<-c("aa","ab", "a")
> a$a
NULL
> a[["a"]]
[1] 3
