-# built-in, only that in case of an empty selection it'll return the default

-# $1: name of variable to be assigned the selected value; it better not be of
-# the form choose_foo to avoid conflict with local variables.
-# $2: default value to return in case of an empty user entry.
-# $3: value to return in case of an invalid choice.

-#
-# PS3="Select one [1]: "
-# choose reply "foo" "ERROR" "foo" "bar" "foobar"

-# If it is empty (i.e. the user clicked Enter) it will be "foo". Anything else
