Optional multispace when next to parenthesis

[Jovansonlee Cesar]

These 2 queries

INSERT INTO user(name, password) VALUES('aaa','xxx');
INSERT INTO user (name, password) VALUES ('aaa','xxx');

are both valid, but nom-sql only parses the 2nd correctly.
I'm guessing this is a bit of complex to do in nom, where the multispace becomes optional when tag!('(') is in the next few bytes.

nom-sql/src/insert.rs

Lines 23 to 40 in 8fe4e92

 table: table_reference ~ 
 multispace ~ 
 fields: opt!(chain!( 
         tag!("(") ~ 
         multispace? ~ 
         fields: field_list ~ 
         multispace? ~ 
         tag!(")") ~ 
         multispace, 
         || { fields } 
         ) 
     ) ~ 
 caseless_tag!("values") ~ 
 multispace ~ 
 tag!("(") ~ 
 values: value_list ~ 
 tag!(")") ~ 
 statement_terminator,

No underlying nom-related reason, just unawareness on my part that this is permitted!

(multispace? generally works fine for an optional space)

I thought the solution was more complicated than that.
