[Lars Ingebrigtsen]

branch: master
commit d608eb1c941aac65d0a1d02b0ac6279e42d8ca8b

Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Guard against faulty flow-filled emails
    
    * lisp/mail/flow-fill.el (fill-flowed): Don't bug out if there's a
    space at the end of the buffer.  This is probably not allowed in
    the flow-fill specification, but has been observed in the wild.
