cli/usage test incorrect?

[rpspringuel]

Why does the usage test not examine the output of calling gregorio without arguments to make sure the usage message is actually being printed? Right now all it does is return the exit code of calling gregorio, which, at least on my system, is 1 when gregorio isn't given a file.

I get a 0

elijah: ~$ gregorio-6_0_0 
gregorio-6_0_0: missing file operand.
Usage: gregorio-6_0_0 [OPTION]... [-s | INPUT_FILE]
Try 'gregorio-6_0_0 --help' for more information.

elijah: ~$ echo $?
0

Okay, so now I'm getting a 0. I think something strange must have been going on with my system yesterday.
