[Rd] Re: make.search.html() without write permission in R.home() (PR#6663)

[Prof Brian Ripley]

We'll fix the error message (it has been fixed once before, but it must
have got broken in another fix), but see the rw-FAQ.  Your private library
area will not show up in the HTML search index even if you had write 
permission: that index is only for the main library (used in the correct 
sense).

We need better information to be able to understand (let alone fix) the 
final part.

There should be, if you mean *packages*.  What exactly does not work?
