print0 concatenates the result into a single argument

... and xargs -0 separates the stream from find -print0 into a list, independent from $ENV{IFS}. Your code will FAIL when the filenames contain characters found in $ENV{IFS}. The find -print0 | xargs -0 pipe won't, because it uses the only character not allowed anywhere in a path name to separate the file names, ASCII NUL.
