I may be guilty of crying wolf when there is none. If I configure the
27.1.91 pretest for lucid and "make", the effect does occur on launching
emacs via src/emacs. However if I go the next step and "make install",
the effect does not occur when I launch the installed emacs. I 
will double-check this by installing from the git master branch and
report back.

I am sorry. I stupidly assumed launching emacs from an src directory
would give the same beast as launching from the installed bin directory.


Best wishes,
