error in example for zenity progress dialog

[Peter Troesch]

'cancel' button does not work
in /usr/share/gnome/help-langpack/zenity/en_GB/progress.page example

the return code tested is -1 "An unexpected error has occurred." rather than 1 "The user has either pressed Cancel, or used the window functions to close the dialog."

change
if [ "$?" = -1 ] ; then
to
if [ "$?" = 1 ] ; then

or maybe
case $? in
    1)
        zenity --error \
          --text="Update canceled."
    ;;
    -1)
        zenity --error \
          --text="An unexpected error has occurred."
    ;;
esac
