 In other words, there are rather recent changes w.r.t. to
 `message' that make the once working code
 crash.


The relevant change in emacs 25 is this:
http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=c63246628461f748d66a8a07ba008de2e00fd33a
'Obey coding-system-for-write when writing stdout/stderr in batch'

and part of the recent breakage is that, there is already a `message' before 
the two new ones I tried to add.
There is another recursion somewhere else related specifically to big5 input 
which I have
not pinned point yet, but I'll just continue in the cjk list.
