I've made a change further in both the v5-10 branch and the
trunk so that the decoder might do so.  Although that behavior
is different from FLIM which I always relied on as a model, it
doesn't seem to cause any harm as far as it is done in Gnus
because `\' in a quoted string is now encoded into `\\' when
sending a message.

Miles, I'm sorry to bother you again but please merge it to the
Emacs CVS.  Thanks in advance.

I agree.  And it is supposed possible to achieve.  However, I
think we should not start such a development in the Emacs CVS
*now* since appearing of `\'s doesn't look so serious to me and
it seems to require that it is tested thoroughly.

I don't yet know how it is easy or difficult.  So, I vote for it
as well.
