After discussing this on IRC, I just thought of another alternative.  We
could add a pair of functions to update-grub_lib, like:

begin_menuentry ()
{
  title=$1
  echo "menuentry \"$title\" {"
  echo "do some env-edit magic"
}

end_menuentry ()
{
  echo "}"
}

then have each of the /etc/grub.d modules that add menuentries use these
functions instead of creating the menuentry directly.

As a side-effect benefit, the /etc/grub.d modules become a bit more
readable.
