Thanks for the suggestion, but we cannot justify
adding such an option when using standard Unix idioms,
one can gain the same effect by running a command like this:

  find . ... -print0 | xargs -0 grep ...

or if you have a list of newline-separated file names in a file named
FILES, run this:

  tr '\n' '\0' < FILES | xargs -0 grep ...
