Refine the patch to make checkstyle happy.
I was looking for some code fomatter for Calcite but I didn't find any
(https://mail-archives.apache.org/mod_mbox/calcite-dev/201510.mbox/%3CCAKa9qD=tycnpddqocfzfxq-4wfv7nkatihfhmumkeztiumj...@mail.gmail.com%3E).
I also tried google java code formatter, which will bring massive blank
character changes to existing calcite code.
I find it hard make calcite's checkstyle happy without a standard code
formatter, especially when my intellij is configured with code formatter from
other projects. Any suggestions?

> When I add multiple partition columns to a window function:
> {code:xml}
> @Test public void testSelect() throws SQLException {
> checkSql("model", "select NAME,DEPTNO,count(*) over (partition by
> NAME,DEPTNO) from EMPS");
> }
> {code}
> Following exception is thrown:
> {noformat}
> java.sql.SQLException: Error while executing SQL "select NAME,DEPTNO,count(*)
> over (partition by NAME,DEPTNO) from EMPS": Error while compiling generated
> Java code:
> {noformat}
> However the document from calcite.apache.org/docs/reference.html states
> multiple partition columns should be allowed:
> {code}
> windowSpec:
> [ windowName ]
> '('
> [ ORDER BY orderItem [, orderItem ]* ]
> [ PARTITION BY expression [, expression ]* ]
> [
> RANGE numericOrIntervalExpression { PRECEDING | FOLLOWING }
> | ROWS numericExpression { PRECEDING | FOLLOWING }
> ]
> ')'
> {code}
> After searching it seems no one is reporting the same issue. I'm opening this
> JIAR as a placeholder, will try to fix this issue
