[gnu.emacs.bug] upcase-region etc. mark empty buffer changed

fpb@sunpitt.east.sun.com (Frank P. Bresz) (02/24/90)

In GNU Emacs 18.52.9 of Thu Feb  1 1990 on ittc (berkeley-unix)

I have also noticed another problem.  And that is that if you perform a
case fiddle operation i.e. downcase-word and the word already is completely
lower case it still marks the buffer as having been modified even though it
hasn't actually done anything.
