Unless a command has separate --nul-terminated-{input,output}
options, the --nul-terminated-records (-z) option should apply
to both input and output for consistency. The caller knows that its
input paths may need to be protected for LF, and the program shows
these problematic paths to its output.
The code already did the right thing. Only the help text needs
fixing.

Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

This works in a similar manner to git-check-attr.
Thanks to Jeff King and Junio C Hamano for the idea:
