tests/libcurses: error out on trying to parse /dev/zero 

Be strict when parsing the tests.  Any unknown character is an error.
This avoids an endless loop when running "./director /dev/zero".  There
is no point in silently ignoring other invalid characters as well, as
this would only leave potential test writers in an unclear state,
without any benefit.
