Yes. The message should in fact never have a null terminator, because
code that assumes it won't work with non-C/C++ apps.

At the same time it's pointless to ask C apps to work with
length-specified strings since none of the standard libraries can
handle it. Thus, a useful API has to convert to/from ASCIIZ, which is
why I introduced the notion of "0MQ strings", so we know what we're
converting from/to.
