Ouch!  AFAIK, a UUE attachment shouldn't have an end line if it's not the 
end of the attachment.  So pan's doing the right thing as you explained, 
and whatever user-agent whoever it was that sent that post is using, is 
sending corrupt UUE.

OTOH, AFAIK UUE was never actually formally standardized and there are 
several variants in the implementation as a result.  This would 
apparently be one of them.

If pan's displaying it correctly, and as previously stated it uses 
different code for handling display vs save (and that does fit with what 
I know of pan from remarks over the years, tho I'm not a coder and rarely 
look at code myself), then perhaps the thing to do, for a coder that can 
actually read what's going on anyway, would be to look at how the display 
code handles it, and use the same technique on the save code, creating a 
patch as appropriate, then filing it in pan bugzilla as well as posting 
it here for K Haley to include in his repository.
