Previously, when called without any arguments, the application required
user input to finish. However, testdisplay is ran by "make check", and
it is not a good idea to run a program that requires user input in "make
check". So we change the default behavior to something that doesn't
require user input. You can still access the previous behavior using the
"-m" argument.
