I didn't but I do now.  Much better!  Thanks!  :-)

A couple of things that we might not want:

* No space before or after binary operator

  We have "good" examples in README.Coding without spaces around binary
  operators.  For example, in a for-loop and in a calculation involving
  sizeof().

* Parenthesized return expression

  We don't have a rule against this.

  In all the simple cases, doing this is bad style.  However, for a
  complex expression it might provide clarity.

  For example, in the same way that:

    x = (y.foo == z.bar);

  gains clarity from the parentheses, I think the following does too:

    return (y.foo == z.bar);

  Or, perhaps, the latter is against the guidelines because we should
  be doing:

    ok = (y.foo == z.bar);
    return ok;

  However, since we have access to y.foo and z.bar in a debugger, we
  can easily check what the return value will be, so I think the
  original is OK.

  Not sure...  :-)

peace & happiness,
