Because the shell makes a distinction between set and unset variables.
The programmable completion code takes care to make sure that the
variables it sets are only set when programmable completion is executing
shell functions or commands.  These variables will be set while compgen
is running, but, since they depend on the readline state, may not contain
useful or current values.
