>Description:

The mvscanw test case of the lib/libcurses/t_curses test is failing
on multiple testbeds:

  http://releng.netbsd.org/b5reports/i386/2019/2019.07.05.06.19.49/test.html#lib_libcurses_t_curses_mvscanw
  http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2019/2019.07.05.17.14.48/test.html#lib_libcurses_t_curses_mvscanw

Looks like the test was re-enabled by this commit:

  2019.06.30.22.21.33 blymn src/tests/lib/libcurses/t_curses.sh 1.16 

with the commit message "Enable mvscanw test since libcurses is now correct."

>How-To-Repeat:

Run the ATF tests.
