[Rd] html help fails for named vector objects (PR#9927)

   help(letters, htmlhelp=TRUE) fails.

Under the Mac OSX gui, the message is 'Help for the topic "a" was not found.' Under the version documented below, and under Windows, the message is

"No documentation for 'a' in specified packages and libraries:"
repeated for all the elements of letters, then followed by

"you could try 'help.search("a")'",

again repeated for all elements of letters.

The outcome seems similar for any character vector (including matrix) object, e.g. the matrix 'primateDNA' in the DAAGbio package.

The following have the expected result

   help("letters", htmlhelp=TRUE)
   help(letters, htmlhelp=FALSE)

The same result is obtained with R-2.5.1.
