in reply to On what column do you wrap your code?

It depends on the code. HTML for instance tends to get wrapped around column 80, except where that would break up an entity in an undesirable way. I tend to wrap elisp around column 120 or so. Perl code gets wrapped based on semantics, not column numbers. email is not, strictly speaking, code, but I tend to wrap it around column 70, because although *my* mailreader can correctly rewrap quoted text, some people with whom I correspond use lesser mailreaders. All of this changes in a web forum, where I use the width of the textarea as a guideline.
