From: Nicolas Graner <nicolas.graner <at> u-psud.fr>
To: bug-gnu-emacs <at> gnu.org
Subject: 24.5; incorrect subject in replies
Date: Tue, 21 Apr 2015 16:35:15 +0200

When you reply to a message whose Subject starts with "Re: ", this is
normally stripped from the Subject before a new "Re: " is added in the
reply. But if the Subject is RFC2047-encoded, stripping does not
happen and you end up with "Re: Re: " in the reply.

Example: a message contains:

  Subject: =?utf-8?Q?Re:_caf=C3=A9?=

Rmail correctly displays it as:

  Subject: Re: café

with a final "e acute". But when you reply to it, the message header
contains:

  Subject: Re: Re: café

instead of just:

  Subject: Re: café

This does not happen when the Subject is entirely in US-ASCII and
therefore not RFC2047-encoded.
