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.
