Yes, you are right.. this is quite new. Some of my
<pkg>/man/*.Rd files have been affected similarly.
AFAIK there is a history behind, where the Rd -> LaTeX
translation code was partly buggy for quite a long time, and hence
such `\`-escapes where necessary in *.Rd such that the produced
*.tex was LaTeX-able.
However, these Rd2latex bugs/problems have been fixed and now
almost all such \-escapes are not only unneeded but actually the
`\` become visible, hence ugly looking
==> hence the NOTE.

In all cases in my packages, just removing the `\` (or
sometimes `\\` ?) was perfect, so I think you can and should do
just that.
