we still have a somewhat fucked up structure here, but that's how we use it at koumbit right now

this code is now tested and works, at least for rdiff. it is assumed that simple flags also works.

get rid of more temporary variables and cleanup

split everything in smaller functions again

remove the $crit and $warn variables, refer to $opt_w and $opt_c since
they are global anyways
