New Revision: 198490
URL: http://svn.freebsd.org/changeset/base/198490

Log:
  Merge r198489 from vendor/ncurses/dist:
  
   Pull upstream patch to fix ee(1) crash when received SIGWINCH:
  
     modify _nc_wgetch() to check for a -1 in the fifo, e.g., after a
     SIGWINCH, and discard that value, to avoid confusing application
     (patch by Eygene Ryabinkin, FreeBSD bin/136223).
