} Grap already does not treat files as an opaque stream of binary octets:
} it imposes/assumes lines terminated by newlines.
A lot of grep implementations will misbehave, core dump, or whatever
if the lines are too long since a lot of implementations will attempt
to read each line into a fixed length buffer. Even if the buffer is
dynamically allocated, what's going to happen if you feed grep a huge
file that doesn't contain any newlines?
