[Rd] correct Rd markup for \value{}

[Gavin Simpson]

Dear DevelopeRs

Several functions in a package of mine have complex returned objects
that are lists within the returned list. I wish to document each of the
components of these sublists.

If I do this within a \value{} section and nest \item within an existing
\item, I get indented R-help sections in the standard help view (eg as
shown by ?foo in Linux), but not in the PDF.

For example:

\item{model}{a list containing the model or non-bootstrapped
    estimates for the training set. With the following components:
      \item{\code{estimated}}{estimated values for \code{"y"}, the
	environment.}
    }
  }

If I add an \itemize (for example:

\item{model}{a list containing the model or non-bootstrapped
    estimates for the training set. With the following components:
    % added \itemize
    \itemize{
      \item{\code{estimated}}{estimated values for \code{"y"}, the
	environment.}
    }
  }

) then these are indented in both the ?foo help and the pdf.

But this has several niggles;:

     1. that the indented \item labels are not left aligned as the top
        level \items are, 
     2. as shown above, I have to manually wrap the labels in \code{ }
        to have them show in typewriter font in the pdf pages (but then
        these appear underlined and wrapped in ' ' in the standard view
        in the terminal), and
     3. that in the standard help viewer in the terminal, I don't get
        the ":" after the sub item labels.

I suspect I'm missing something or trying to do something that is not
possible without the niggles.  I'd appreciate suggestions as to where
I'm going wrong, what documentation I missed or suggestions based on the
experience of others.

Thanks in advance,

G
