Looks good!  I notice that it doesn't exit with non-zero when it
(thinks that it) finds issues in my current branch.  Do we want it to
do that?  Would that be as simple as having warn() set a global?

I don't think that we should error on things that README.Coding doesn't
prohibit, particularly if they appear in "good" examples.  I think this
is particularly true if people are pushing hard for this code to be
used in tests to validate code.  It would be wrong to have tests that
contradict README.Coding.  We could, of course, change README.Coding if
there is a good reason to do so.

I hope that others agree...  :-)

I note that these particular checks seem to be implemented in
cstyle-file.py (via check_binary_operator() and
check_parenthesized_return()), so they should be easy to remove.

peace & happiness,
