You're right, I think it's a bug that grep -zf FILE uses newline
separators in FILE. It should use NUL separators.
This cannot be done for NUL bytes in command-line patterns, though,
since command-line arguments cannot contain NUL bytes.
Indeed. But that merely means that on the command line, when -z is in
effect, you can't specify multiple patterns (but instead have to use -f
FILE if that's what you really want). Meanwhile, the effect on being
able to match a literal newline would be observable from either the
command line or -f FILE.
