That indeed was the intention, and if it is not behaving, you found
a bug.
The relevant code in "sub ask" does this:
...
$resp = $term->readline($prompt);
if (!defined $resp) { # EOF
print "\n";
return defined $default ? $default : undef;
}
if ($resp eq '' and defined $default) {
return $default;
}
if (!defined $valid_re or $resp =~ /$valid_re/) {
return $resp;
}
I am scratching my head wondering why your "just hit enter" does not
trigger the "if response is empty and we have default, just return it"
codepath we can see above. It shouldn't even trigger the regexp
based validation codepath in the first place.
