Thanks, Paul! I've added it to the 1.5 patch page at
http://www.python.org/1.5/errors.html
Note that I've also added an "all.txt" file to the 1.5 directory (not
to its patches subdirectory) that contains all patches -- for those
who would like to apply all patches to a clean Python 1.5 source tree.
