Hi Dave,

For whatever reason, regardless of the mailer I use, when I save your
last file and then try to use it for patching, long lines are getting wrapped,
and patch complains about a malformed patch file.  I don't know why
this happens, because the first patch was usable with no problem?
Anyway, I started fixing each wrap instance by hand, but would it be
possible for you to re-post with the patch file as a file attachment?

Thanks,
  Dave
