So don't indent wrapped predicates or is that just email formatting?

I actually prefer this one with the operators at the front but I'm fine
either way.

This is where choice of editor or IDE comes into play. I use Eclipse so my
left pane is a navigator, the center pane is the editor and the right pane
is search/outline/bookmarks. Even with that, I have my column marker set
at 100 which works well (for me). Still though, there's code, mostly
function prototypes or definitions, that make me nuts because they run well
beyond 100 characters. Even more annoying are header files like
res_pjsip_session.h where both declarations and comments go out to 200
columns.

My vote is 100.

+1000. I can adapt and so can my editor but having real guidelines is key.
