normal-bracket50bracket-normal?

These usually indicate incorrect files. Have you looked at the 
experimental Rd parser in R-devel to see if it pinpoints an error?

For example, in both Fperm.Rd and compareDerivatives.Rd there is an 
\itemize{} construct inside \value, which is incorrect as \value is 
itself an implicit \itemize.  Please do check the description in 
'Writing R Extensions' (and \value is definitely quirky).

Hello:


    I've found structures like "normal-bracket50bracket-normal" in
help files for R packages including the following:

         * "mergeprepare" and "mergematrices" in a document dated
March 3, 2004 by Richard Mott;  the second contains
"normal-bracket30bracket-normal".

Which is insufficient for the rest of us to get access to it.

         * "Fperm.fd" and "tperm.fd" in the "fda" package;  these 
help pages were written primarily by Giles Hooker.

         * "compareDerivatives" in the "maxLik" package;  this help 
page was written by Ott Toomet and me.


    What can we do to eliminate this nonsense comment?

    Constructs like this seem to be generated in perl code used in "R
CMD" processing
(https://svn.r-project.org/R/trunk/share/perl/R/Rdconv.pm).

    Thanks,
