Ok, I can take it out.  I thought since the gnupg configure script
directly references ncurses (when looking for readline), there should
be a direct dependency from gnupg to ncurses, rather than depending on
that dependency being there indirectly.  I.e., what if someone changes
readline's dependencies, would they consider the effect on gnupg?

But perhaps since it's part of readline support that is not necessary.
