Reflowing emails with fmt(1)
scribo(1) can now filter the message body through a command rather 
than writing directly to the file. The advantage to this is that I 
can reformat the mails with, eg. fmt(1), or even turn markdown to 
HTML, or trim HTML tags. So many possibilities !

This fixes the issue I have when sending mails from my phone which 
doesn't wrap text at a given column number. This way I can type 
however I want and rest assured that my entry will be nicely 
rendered !

EDIT: actually it looks nicer when reflowing with fold(1), as it 
won't refill lines.
