update-burg generates wrong burg.cfg

[Stefan Saraev]

after update-burg in resulting burg.cfg I have:
....
function select_menu {
  if menu_popup -t template_popup theme_menu ; then
    free_config template_popup template_subitem menu
    load_config ${prefix}/themes/${theme_name}/theme
    menu_refresh\n fi\n}\nset theme_name=ubuntu
function toggle_fold {
  if test -z $theme_fold ; then
    set theme_fold=1
  else
    set theme_fold=
  fi
  save_env theme_fold\n menu_refresh\n}
...
  controller.ext\nfi
insmod ext2
...

there are few incorrect '\n's
the result should be:

...
function select_menu {
  if menu_popup -t template_popup theme_menu ; then
    free_config template_popup template_subitem menu
    load_config ${prefix}/themes/${theme_name}/theme
    menu_refresh
  fi
}
set theme_name=ubuntu
function toggle_fold {
  if test -z $theme_fold ; then
    set theme_fold=1
  else
    set theme_fold=
  fi
  save_env theme_fold
  menu_refresh
}
...
  controller.ext
fi
insmod ext2
...

I attached a fix.

Thanks, this fix is included in bzr r1820

BTW, there is a small issue with echo -e. Ubuntu's sh points to dash, which doesn't understand echo -e, therefore there is an extra -e in the output file. I have changed it to cat << EOF in r1821, which works in both bash and dash.
