No, I think you covered most of it quite well [including the bit
about "grep -m" not working properly in the case of pipes, sockets,
special files, etc.], thanks.

Yes, I know that "grep(1)" only promises that "-m" works "If the input
is standard  input  from a regular file", but IMHO we would all benefit
from having an option for "grep" (and "head") that would force using
"read(fd,&c,1)" when the user really, really wanted it (them) to.
