[Rd] test fails when requesting LC_CTYPE

[Kasper Daniel Hansen]

I rebuilt R with
  export LC_CTYPE=en_US.UTF-8
and the test still fail.  Surprisingly, when I run R from the bin directory
and execute the test code, it runs without error:

> oloc <- Sys.getlocale("LC_CTYPE")
> mbyte.lc <- {
+     if(.Platform$OS.type == "windows")
+       "English_United States.28605"
+     else if(grepl("[.]UTF-8$", oloc, ignore.case=TRUE)) # typically
nowadays
+       oloc
+     else
+       "C.UTF-8" # or rather "en_US.UTF-8" (? from  system("locale -a|
fgrep .UTF-8") )
+ }
> stopifnot(identical(Sys.setlocale("LC_CTYPE", mbyte.lc), mbyte.lc))
> oloc
[1] "en_US.UTF-8"
> mbyte.lc
[1] "en_US.UTF-8"
