Comment on GNU Emacs

I have used Emacs for at least 25 years on a number of different OS's. It is not part of many Unix distributions and I some times must revert to "vi," the de rigueur editor for pure Unix sys admins.

BTW, many Emacs style commands, e.g., CTL-a (beginning of line), work in Mac OS X text fields. Must have been an Emacs aficionado in one of the Apple development groups.
