The warning for 'assert (cond, msg)' was specifically put in because
this is a nasty trap. It's *always* a mistaken attempt to write
'assert cond, msg' -- usually in an attempt to break a long line

syntax error rather than removing the warning.
Compared to other "lint warnings" this one is much nastier -- it is
also much more certain that it is a mistake. (Much more certain than
e.g. an undefined variable, which could still be legitimate code due
to dynamic updates to globals() or builtins.)
Would there be less chance of confusion if there were some kind of
syntax such as "assert cond with msg"?
