If a lisp function given at the prompt returns a valid type this one is accepted.

If the default argument is given (and it is not nil and the flag contains no bitvalue 1), then empty input is allowed as well.
flag: integer, same as the INITGET flag or nil
kwd: a initget-like string or a list of strings or nil
msg: a string to be displayed as a prompt or nil.
def: a default value as number or nil
Either the default value or any number entered by the user.
