No, it's actually unambiguous with or without the -z option. Without
-z, pathnames with "unusual" characters (whose definition depends on
core.quotePath) will cause the pathname to be enclosed in
double-quotes with the unusual characters handed with backslashes and
control characters. With -z, it separates pathnames with a nul
character instead.

Yep, I'll add a pair and use filenames with multiple tabs.
