Bogus subject encoding (was: Can't isearch ...)

[Reiner Steib]

Stefan, something strange happened to the subject headers of your
messages:

,----[ (a) Peter Dyballa  ]
| Subject: =?iso-8859-1?q?Re=3A_Can=27t_isearch_=27=F6=27?=
| Message-ID: <address@hidden>
`----

,----[ (b) Stefan Monnier ]
| Subject: Re: =?ISO-8859-1?Q?Re:_Can't_isearch_'=F6'?=
| Message-ID: <address@hidden>
`----

Note the bogus "Re: Re: " here.

,----[ (c) Peter Dyballa  ]
| Subject: Re: =?ISO-8859-1?Q?Re:_Can't_isearch_'=F6'?=
| Message-ID: <address@hidden>
`----

,----[ (d) Stefan Monnier ]
| Subject: Re:

=?US-ASCII?Q?Re:_=3D=3FISO-8859-1=3FQ=3FRe:=5FCan't=5Fisearch=5F?==?US-ASCII?Q?'=3DF6'=3F=3D?=
| Message-ID: <address@hidden>
`----

Double encoding.

Stefan, do you use Gnus from current Emacs CVS?  IIRC, rfc2047.el has
been synced with the Gnus trunk recently.

I can't reproduce this, but I don't have the a current version here.

BTW, is the bare quote (') allowed within an encoded word?

Bye, Reiner.
