C# SQL statement formatter class

update a set a.ID = b.ID, Name = b.Name from Table1 a inner join (select ID, Name from Table2 where Active <> 0 and Current <> 0) b on a.ownerid = b.ownerid and a.type = b.type and b.version = '87.1' and a.Name is Null where a.expired <> 0 

becomes

update a set a.ID = b.ID,	Name = b.Name from Table1 a	inner join	(	select ID,	Name	from Table2	where Active <> 0	and Current <> 0	) b on a.ownerid = b.ownerid and a.type = b.type and b.version = '87.1' and a.Name is NULL where a.expired <> 0 

The solution includes a simple winforms demo executable along with the Formatter class. The implementation of the formatter employs a number of routines from unrelated libraried code; I've pulled these fragments into an additional file: LIB.cs.
