143,System.Process readProcess incorrect documentation of return value,benc,,"The System.Process docs here:

http://haskell.org/ghc/docs/6.12.2/html/libraries/process-1.0.1.2/System-Process.html#v%3AreadProcess      

describes the return value as:                                             
                                                                                
> returns either the output string, or, in the case of non-zero exit            
> status, an error code, and any output.                                        
                                                                                
and the given example output is:                                                
                                                                                
>   Right ""Thu Feb  7 10:03:39 PST 2008\n""                                      
                                                                                
This suggests that the return value looks like:                                 
                                                                                
IO (Either ? String)

But the return type is shown (in that same documentation, and in ghci 6.12.3) as IO String, and my own experimentation shows no ""Right"" being returned in the case of a successful operation - instead I get only the String containing the program output, not wrapped. 

Perhaps this is historic.
