Re: Bug#728501: w3m-el: mew-w3m-region & multiple blockquote



Hi,

As an alternative solution, I have been using the replacement of
`mew-w3m-region` below.  Comments are welcome.  I had no time to try
the proposed patch yet.

My 0.02,
C.


(defun mew-w3m-insert-quote-mark ()

to the data.  This is to put the quotation mark right before the
text."

	    (tagend (match-end 0)))

	 ((string-equal tag "br")
	  (goto-char tagbeg)
	  (insert mew-w3m-region-cite-mark)
