line width?

[drew]

I'm somewhat of a newbie.  I'm using Mutt 1.2.5 and vim.  I would like to set a wrap 
length for my messages at an attractive 60 or so columns.  It seems like the only 
thing I've read that you can do is get an external paragraph formatter like par and 
run it on the message before you send it.... is that the best way to do it, or am I 
missing some simple feature of vim?
