Lennart, thank you,

I set grep-use-null-device to nil, but the problem still happen.

Maybe I shall trace the code to find how to avoid grep-probe. There is no
switch to turn off (grep-compute-defaults) in grep, because different
versions of grep. But I think most of people work on Linux and Gnu grep. So
why not have a switch tell it do not compute defaults?
