[Rd] dir.create does not return a value (PR#13686)

[r.hijmans at gmail.com]

?dir.create  (part of the base package) says that:
"dir.create and Sys.chmod return a logical vector indicating which
operation succeeded for each of the files attempted"

However, on my system it returns nothing  (whether successful or not):

> dir.create(":::@!#!::")
> dir.create('b')
