New Revision: 198489
URL: http://svn.freebsd.org/changeset/base/198489
Log:
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).
