Or a message could contain information about whether lines should be 
filled and word-wrapped. Like this message you're reading, for example. 
It's text/plain format=flowed (RFC 3676). The English text is marked to 
be filled and word-wrapped on display. The C program at the end is not.

Unfortunately, not many mail readers implement text/plain format=flowed. 
Thunderbird does; Mutt has partial support; an obscure mail reader named 
Trojita does. There may be others I don't know about.

Here's a picture of how Thunderbird displays this message: 

#include <stdio.h>

int main(int argc, char *argv[], char *envp[])
     for (;;)
     return 0;
