Incorporating the diffs for buffer.c, indent.c and xdisp.c below will
cause emacs to display 255 character fonts (newline is special) in
buffers with local variable ctl-arrow set to any value other than T or
NIL.

This change will be obsolete when version 19 is released, but it is
nonetheless useful for the time being.  It has been pointed out that
answering questions about the availability of version 19 takes time
away from writing the code, so please be patient.

By the way, I have been told that these diffs can not be automatically
incorporated into source files.  Forgive my ignorance of the proper
commands and be glad that the changes are small.
