Dear devs,

A control sequence that only contains a single null byte is not correctly stringified. Comparison between Knuth TeX and LuaTeX:

   $ tex test.tex    ! \^^@.    l.2 \errmessage{\string\^^@}

   $ luatex test.tex    ! \.    l.2 \errmessage{\string\^^@}

MWE:

   \catcode0=11    \errmessage{\string\^^@}    \bye

looking at it.
