Sorry for all the ruckus. It did indeed appear to be 'proper' to me, but
I can pinpoint a very specific example that lead to my investigation:

/var/lib/dpkg/info/realtimebattle.prerm
#!/bin/sh
# Prerm

case "$1" in
  remove|upgrade|deconfigure)
    install-info --quiet --remove /usr/info/realtimebattle.info
  ;;

  failed-upgrade)
  ;;

  *)
     echo "prerm called with unknown argument \`$1'" >&2
     exit 0
  ;;
esac

# Automatically added by dh_installdocs
if [ \( "$1" = "upgrade" -o "$1" = "remove" \) -a -L /usr/doc/realtimebattle ]; then
        rm -f /usr/doc/realtimebattle
fi
# End automatically added section
# Automatically added by dh_installdocs
if [ "$1" = remove -o "$1" = upgrade ] && \
   command -v install-docs >/dev/null 2>&1; then
        install-docs -r realtimebattle
fi
# End automatically added section

Everything looks fine, right? Note if this package is purged or removed, neither
of the Automatically added lines will exec. The only indication I could find as 
to why not, lead to me believe the quotes were not parsed correctly.

Good quotes or bad, this package and any others formed this way will not exec
the Automatically added portions on remove or purge on my machine.
Kernel 2.2.17, bash 2.04

I was just suggesting the quote change due to the fact that they actually work
after making the suggested changes.

Sorry for longwindedness... Just trying to help.
