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.
