Awesome: A window manager that gets out of the way

For me, mutt can rewrap, but slrn does not (there's also some interesting failures to decode messages where =20 ends nearly every line...). I don't know if things have changed since I was using KDE's PIM suite, but KNode and KMail would wrap to the setting or the editor window's width, whichever was less. Since there's no "message preview" before sending, it caused quite a bit of interesting mail formatting. Took me a month or two to track down the culprit. Luckily, Vim has the 'gq' command to rewrap paragraphs and makes rewraping a breeze if needed. The worst is when hard line wrapping happens, but the quotation markers aren't copied to the wrapped line (slrn can collapse quote blocks and the feature is broken with such mails).
