[Rd] Bug in help(package=) (PR#7923)

[murdoch at stats.uwo.ca]

The following is a bug or mis-design in help(package=):

 > showhelp <- function(packageName) help(package=packageName)
 >
 > showhelp("utils")
Error in .find.package(pkgName, lib.loc, verbose = verbose) :
         none of the packages were found

The problem is that it calls library(help=) with argument "packageName" 
instead of "utils".  Unlike library(), it has no character.only argument 
to force interpretation of the packageName as a character vector.
