commands: wrapped docstrings at 78 characters We have always had a left margin of 4 characters -- probably just because that's how docstrings for top-level functions turn out by default, but it also looks nice in the built-in help. The docstrings were wrapped at 70 characters, which is the default for Emacs. However, this gives a right margin of 10 characters in a standard 80 character terminal. I've now wrapped the relevant docstrings at 78 characters, effectively killing the right margin. The asymmetric margins looked a bit odd and some of the text looked cramped with a right margin, so Dirkjan and I felt that it was best to remove it entirely. The two character gap was kept to have some space between the border of the terminal -- it will also make diffs involving the docstrings fit in a 80 character line.
