From d608eb1c941aac65d0a1d02b0ac6279e42d8ca8b Mon Sep 17 00:00:00 2001 From: Lars Ingebrigtsen Date: Fri, 11 Sep 2020 16:45:12 +0200 Subject: [PATCH] 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. --- lisp/mail/flow-fill.el | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lisp/mail/flow-fill.el b/lisp/mail/flow-fill.el index f4b55031194..b357b3e2563 100644 --- a/lisp/mail/flow-fill.el +++ b/lisp/mail/flow-fill.el @@ -157,7 +157,8 @@ lines." ;; Hack: Don't do the flowing on the signature line.
