Coding style guidelines

Is there any coding style guidelines for TortoiseSVN?

Most of them can be glanced from existing code, but, for example, I
just found out that Stefan prefers class member functions to file
scope functions. If I would know that, surely I would code it
according to his preferences ;-)

On a related note, is it really necessary to parenthesize even single
variables and function calls in inside conditionals? For example is,
                if ((!bLogRes)&&(!m_path.IsUrl()))
really preferred to
                if (!bLogRes && !m_path.IsUrl())
?

I realize this topic is highly "flammable", so I will follow whatever
guidelines are accepted, just wanted to re-confirm unusual ones.
