How can I suppress this warning?

Warning: a final empty element has been omitted the part of the args list of 'list' being evaluated was:

   (1, 2, 3, )
[[1]]
[1] 1

[[2]]
[1] 2

[[3]]
[1] 3

> suppressWarnings(list(1,))

Warning: a final empty element has been omitted the part of the args list of 'list' being evaluated was:

   (1, )
[[1]]
[1] 1

And can anyone add some insight as to why this warning was added? It was nice to be able to use a construction like:

a <- list(
 b = 3,
 c = 4,
)

so when you added a new line, you could just copy and paste an existing line.
