Thanks, but as a stand-alone patch, that makes grep fail to compile,
because there is one remaining use of the variable whose declaration
is removed.

In any case, there is some ambiguity in the documentation
about what "line" buffering means with -Z. With -l and -Z, should
grep --line-buffered flush after printing each <file_name, NUL> pair?
That's what I'd expect.
