[Rd] parsing Rd files and \deqn{}

Hi
[R-2.9.0]
I am having difficulty including a LaTeX formula in an Rd
file.
The example given in section 2.7 in 'Parsing Rd files' is:
\deqn{ f(x) = \left\{
\begin{array}{ll}
0 & x<0 \\
1 & x\ge 0
\end{array}
\right. }{non latex}
For me, this gives:
\deqn{ f(x) = \left\{
\begin{array}{ll}
0 \& x<0 \bsl{}
1 \& x\ge 0
\end{array}
\right. }{}
in the tex file, which is not desired because the ampersand
is escaped; the '&' symbol appears in the dvi file, and I
want an ampersand to indicate alignment.
Also, the '\\' appears as \bsl{}, which is undesired; the
resulting dvi file (made by R CMD Rd2dvi) looks wrong.
How do I write the Rd file so as to produce non-escaped
ampersands?
