In the Emacs master branch (i) emacs -Q (ii) C-x C-f emacs/src/syntax.c (iii) C-M-s \(inc\|dec\)_both (iv) Press C-s a few times. Notice that the highlighting of the found match has the purple background over the correct characters, but the characters displayed in the foreground are " _both". This incorrect display is a bug. (v) Press a few times. The lazy highlighting is now correctly displayed each time. (vi) Note that if one starts at the end of the buffer with C-M-r, etc., the same problem occurs. -- Alan Mackenzie (Nuremberg, Germany).
