I totally agree with this. Frankly, I don't think its too much to ask people to use modern software that is capable of very basic functionality like wrapping text. I find 72-column text with arbitrary (in the sense that the line breaks are at character-boundaries, not paragraph boundaries) line breaks incredibly hard to read.

For example:

  I guess it also depends on who your audience is. Most of the devs I've
  worked with use modern software, so long lines have never been an
  issue for me. I could see where some teams would have a culture of 
  using more basic tools that it would become more of an issue. Of 
  course, typography plays a role, too. I don't generally use a 
  monospace font for reading normal text, and proportional fonts seem 
  to work better with this outdated style.
