I'm not quite sure of it but FLIM's decoder (which SEMI MUAs
such as Wanderlust uses) does so, and I followed it.

I agree that `\\' in a quoted string is decoded into `\'.
However, I don't think it is useful that

"foo \"bar\""  is decoded into  "foo "bar""  or  foo "bar"

because it may appear in the From header and may be used in the
To header when replying.
