What kind of program is "ag"? What does it do, and how?

Does "ag", whatever it is, behave differently depending on whether its
standard output is a console device or something else?
Also, are you sure the same "ag" is run in both cases? The first
command didn't include the absolute file name of the program, could it
be that cmdproxy found some other copy of it?
