================================================================
Dear Bug Team!
I have found a bug in the XEmacs package "vm":
RFC 2047 requires in its section 5 that "encoded-words"
must be separated from ordinary text by linear white space
but "vm" fails to do so.
The bug in in function "vm-mime-encode-words" (from "vm-mime.el").
It can be reproduced by a call to "vm-mime-encode-words-in-string"
(which internally calls "vm-mime-encode-words"). Example:
(vm-mime-encode-words-in-string "aÄoö")
---> "aÄoö"
The correct result would be:
"aÄoö"
This bug seems to be fixed in the "vm" trunk version
("http://bazaar.launchpad.net/~vm/vm/trunk/view/head:/lisp/vm-mime.el").
I have copied over "vm-mime-charset-to-coding" and
"vm-mime-encode-words" (from "vm-mime-el") and
"vm-mime-encode-headers-words-regexp" (from "vm-vars.el") into
my XEmacs installation and initial tests look promising.

OK, thanks! Super-busy for the next few days, but I'll take a look
after that. Since our current version is apparently woefully out of
date, it wouldn't hurt to release an interim version that's not
intended to be updated, but rather completely replaced by a new
upstream version.
I'll let you know if we make progress on that.
Steve

This bug seems to be fixed in the "vm" trunk version
("http://bazaar.launchpad.net/~vm/vm/trunk/view/head:/lisp/vm-mime.el").
I have copied over "vm-mime-charset-to-coding" and
"vm-mime-encode-words" (from "vm-mime-el") and
"vm-mime-encode-headers-words-regexp" (from "vm-vars.el") into
my XEmacs installation and initial tests look promising.
Meanwhile, I have encountered very strange behavior:
After the above change, "vm" can no longer persist
mark changes for some messages which use RFC 2047.
Example:
A message is newly received and marked with "N" ("new").
I read the message, the mark is correctly changed to " ".
When I then save the folder, leave "vm" and reenter "vm",
the message may again be marked with "N".
It seems that not all messages using RFC 2047 are affected, only
some of them.
I have no idea how my change could result in this behavior: the
changed functions affect only encoding and should have nothing
to do with mark handling. Maybe, the "X-VM-v5-Data" got somehow confused
by the change.
For the moment, I have reverted to the old state.
I may come back in the future when I have found time to look more
closely into this behaviour.

Don't waste your time looking into it unless you get it with a recent
vm.
If you like, I can send you the vm I'm using, which is almost maybe
nearly what the 8.2.0 release will be.
