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

Not if that would screw up the screen. This is a real problem with
arbitrary binary data, with real security implications.
If the output is displayed through a util like 'less', such binary data
is automatically filtered.
Perhaps it would be a good idea for grep to provide such filtering
(displaying <00><AH>, or such) for non-ascii data?
I have a command to restore my tty settings to the value they
were when I logged on.
Nevertheless, displaying <filename>: matches, without the text doesn't
seem to pose any security risks.
