indentation, line length, trailing whitespace

[Jared Johnson]

Hi,

Is there any interest in patches to conform current QP code to line 
length and whitespace standards?

1.  I notice that most of the codebase uses 4-space indents, but I have 
seen some areas with 2-space indents and tab characters.

2.  It's been pointed out that it is preferred that lines are kept to 80 
characters are less, but this is violated in a number of places.

3.  Robert Spier recently committed a cleanup to a lot of trailing 
whitespace in Qpsmtpd.pm, but such trailing whitespace still exists in a 
lot of places.

Our organization conforms to similar coding guidelines WRT these issues 
and I would be happy to submit patches to cleanup up each of these areas 
if there's any desire.  I would also suggest creating a 'coding 
guidelines' page on the wiki for this and any other style issues that 
are deemed useful to conform to.
