OK, but in future please make a separate report for each issue when
you have more than one.

This is already fixed. Try the trunk from

http://savannah.gnu.org/projects/emacs/

or the 23.2 pretest from

http://alpha.gnu.org/gnu/emacs/pretest/emacs-23.1.92.tar.gz

Details are lacking, but this appears to be a problem with "highlight
completion" from http://www.math.washington.edu/~palmieri/Emacs/hlc.html.
Since this isn't part of Emacs, please explain exactly how to
reproduce the error, starting from `emacs -Q'.
