Martin Maechler asked me to restate my problem.

Compiling the file (slightly modified w.r.t. the formerly
attached file) that can be found at
     http://www.geo.uni-bayreuth.de/~martin/filetransfer/xswms2d.Rd
terminates with the error message

******* Syntax error: mismatched or missing brackets in
/-----
  .....
\-----

when compiled by
    R CMD Rdconv -t txt xswms2d.Rd

However, the file does not cause any error after deleting the
line
      \item{a}{4}
(line 530), for example. This line is within the simple
environment
     \itemize{
       \item{a}{1} % if this line or
       \item{a}{2} % this line or
       \item{a}{3} % this line or
       \item{a}{4} % this line is deleted no error occurs
     }

Although there might be an error in my Rd code, the
appearance (or not appearance) of the error message is
surprising, and the reason for the error is not clear
from the message.
