The '-' symbol means that portage will rebuild ncurses without tinfo -- exactly like your existing build of ncurses :) Makes perfect sense if you happen to be a computer. My favorite peeve is when a libreoffice useflag is added for, say, support for Swahili or Urdu, and now I'm forced to rebuild all of libreoffice just to re-install libreoffice without support for Urdu or Swahili. If I were a computer I'd agree immediately with that reasoning.
