They're not. The '--binary-files=without-match' option enables that 
behavior. With that option, this issue doesn't come up.

if they want to scan binary files as
well as text, then positive results should be printed to stdout

Not if that would screw up the screen. This is a real problem with 
arbitrary binary data, with real security implications.
