[whups] Email wordwrap patch

[Mike Baptiste]

Below is a patch which changes how comments are formatted in 
notification emails.  The current code strips out all line feeds and 
outputs the comment in 80 char chunks.  While this made for a compact 
email, it really scrambled stuff like code snippets, data lists, etc

So instead of packing the comment down, we just wrap any long lines 
using wordwrap.

I realize this is a change vs a bug fix.  If there are folks that prefer 
compressed comments, maybe we can make it an option.  One thing I did 
notice is the current code didn't replace the linefeeds with spaces so 
words got joined together that had linefeeds between them. This would be 
fixed by adding a space to $result in the while (pos) loop I think.

Anyway, here is the patch
