Re: Auto Fill Comments

[Christopher Dimech]

Because I thought that I can have a keybinding that cycles
auto-fill.  It could be long and hard to do that for every
major mode.

There are times when I need to also have the code use auto-fill,
but not always.  A keybinding cycle could be a solution for every
major mode.
