[Rd] redundant "`" symbol in the name of list (R version 3.5.0 & 3.5.1)

[ya wei]

Dear R devel Team,

There might be a bug in the function "list" for R version 3.5.0 & 3.5.1.
For the toy example

```
> list(c=2, d=3)
```

The output is

```
$`c`
[1] 2

$d
[1] 3
```

The name of the first variable "c" would come with a redundant "`" symbol.
I also have tested it on some older R versions, say 3.4.4, it turns out to
be OK, no redundant "`" symbol.


I am looking forward to your reply.


Best,
Fans of R
