Characters per line for technical documentations
I was wondering what will be the best choice for the number of characters per line for text based technical documentations. Well, better to reduce the scope of question. Ok, let it be a documentation for Python package/product written using ReStructuredText. My choice is now 80 characters. Any reason to reduce that or not use a character limit at all? Python PEPs are using 72 characters, is there any style recommendation from Python coding or other standards? I started thinking about this from https://launchpad.net/products/bzr/+bug/39657
