[arch-dev-public] [signoff] ncurses-5.7-2

Upstream update. From the homepage: "This release is designed to be upward compatible from ncurses 5.0 through 5.6; very few applications will require recompilation, depending on the platform." Version 5.7-2 fixes the packaging of the non-wide character libraries My 64 bit laptop is away so I require someone to build for x86_64. Thanks. Allan
