Suppressing options that come from the "Quit" panel button?

[Adam Funk]

The quit button in the GNOME panel brings up a bunch of choices (Log
out, shut down, restart, etc.).  I have occasionally clicked on "Shut
down" by accident instead of "Log off" --- is there any way to remove
the options I don't want?

(Ideally I would like to see only "log out", "lock screen", and
"switch user"; then I could shut down or restart from the GDM menu.)
