Error when a foreign key clause does not include column names

What steps will reproduce the problem?
1. With an other tool, create a database with the following tables:
CREATE TABLE a(x int);
CREATE TABLE b(y int references a);
Note that I simply wrote "references a", not "references a(x)".
2. Open the database in the SQLJet database browser

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Version 1.1.10 (also tested with nightly builds)

Please provide any additional information below.

The bug is in the parser, on the rule "fk_clause" : the syntax accepts the 
eventuality that there is no columns declaration (code between parenthesis is 
followed by "?") while the rewriting rule does not: if I replace (COLUMNS 
$column_names+) with (COLUMNS $column_names*) it seems to work, but I did not 
test if it has other effects.

Note that foreighn clause without columns is explicitly accepted by SQLite's 
syntax :
