For Gopher: make VIM automatically wrap at 67 characters...
in ~/.vimrc
###########################
set textwidth=67
#############################
if you want to re-wrap existing text to this width...
<esc>
gg (to go to the top of the file)
gqG (to re-wrap)
to help with other stuff:
#################################
set backspace=indent,eol,start
syntax on
set hidden
