[Libguestfs] hivex: hivexsh dependency on libncurses?

Hopefully this is my last issue raised as a result of the Debian packaging effort! I see a warning from debhelper which suggests the linked library "libncurses" may actually be no longer required by "hivexsh". Is this so, or is it in preparation for some future use of the library? dpkg-shlibdeps: warning: dependency on libncurses.so.5 could be avoided if "debian/hivex/usr/bin/hivexsh" were not uselessly linked against it (they use none of its symbols).
