1) I've just looked at "/etc/grub.d/30_os-prober" and it's changed
since I posted [1].

With 12.04, you have insert the lines to exclude the Windows Recovery
partition(s) between

<begin>
if [ -z "${LONGNAME}" ] ; then
 LONGNAME="${LABEL}"
fi
</end>

and

<begin>
gettext_printf "Found %s on %s\n" "${LONGNAME}" "${DEVICE}" >&2
</end>


2) The ouput of os-prober seems to have changed yet again because
according to [2], it now prints

<begin>
Found Windows Recovery Environment (loader) on /dev/sda1
Found Windows 7 (loader) on /dev/sda2
Found Windows Recovery Environment (loader) on /dev/sda3
</end>
