advertised-undo failure and testcase


From: Andrew M. Scott

advertised-undo after a kill-region fails on the attached file with
"No undo information in this buffer", though C-y "yank" has the text.
I think it's some kind of coding-related issue.  The attached file has
been gzip'd and uuencoded.

I first noticed this issue on CVS Emacs builds beginning Sept 12 (it
may have been there earlier); it's still there through yesterday's
build (Sept 28, 2006).

To reproduce.
1. uudecode and guzip the attached undo-testcase.gz.uue
2. emacs -Q &
3. C-x C-f undo-testcase
4. select a region containing the last three lines
5. C-w (kill-region)
6. C-x u (advertised undo)
Minibuffer says
"No undo information in this buffer"
7. C-y (yank) pastes in killed text.

I ran C-u C-x = on the first two non-standard characters
in the undo-testcase file; these are:

  character: =83 (131, #o203, #x83, U+0083)
    charset: eight-bit-control (8-bit control code (0x80..0x9F))
 code point: #x83
     syntax:    which means: whitespace
buffer code: #x83
  file code: #x83 (encoded by coding system raw-text-unix)
    display: by this font (glyph code)
     -Adobe-Courier-Medium-R-Normal--18-180-75-75-M-110-ISO8859-1 (#x83)

  character: =8c2 (194, #o302, #xc2)
    charset: eight-bit-graphic (8-bit graphic char (0xA0..0xFF))
 code point: #xC2
     syntax:    which means: whitespace
buffer code: #xC2
  file code: #xC2 (encoded by coding system raw-text-unix)
    display: by this font (glyph code)
     -Adobe-Courier-Medium-R-Normal--18-180-75-75-M-110-ISO8859-1 (#xC2)
