dh_installinfo not created postinst entry

[Peter S Galbraith <GalbraithP@dfo-mpo.gc.ca>]

I'm calling dh_installinfo on potato:

 dh_installinfo -a doc/gri doc/gri-? doc/gri-??

I do get files copied correctly to ./tmp/usr/share/info/ but I do
not get an `install-info' script line added to
debian/postinst.debhelper and debian/prerm.debhelper

The dh_installinfo man page says I should, but it doesn't say
where the required info is gathered from (e.g. the
debian/packagename.info file for debmake).

(I don't really mind creating my own postinst file, I'm just
trying to get things right the best I can.)

Thanks,
