Are you reading this out of the source of a LaTeX document? In LaTeX,
the notation \verb|foo| means to print the foo verbatim, in a monotype
font, without interpreting any of the contents as "special" (and
backslashes are *very* special in LaTeX). More likely, the formatted
output would look like
tr '\0' '\n'
which would try to transform null bytes in the input into newlines.

Right, that makes sense here.
