test file (open with umbrello, do a codegen)

Version:           unspecified (using Devel) 
OS:                Linux

160	    sql<<m_endl;
161	    sql<<"-- CHECK Constraints are not supported in Mysql ( as of version 5.x )";
162	    sql<<m_endl;
163	    sql<<"-- But it'll parse the statements without error ";
164	
165	    // call base class
166	    SQLWriter::printCheckConstraints( sql, constrList );

There should be a newline somewhere on lines 163/164.
Else, part of line 166 output could be commented out by line 163, as it does not always begin with a newline.

Reproducible: Always

Steps to Reproduce:
Download attached *.xmi file, open it, do a codegeneration (MySQL).
Look at the end of object2.sql. 

Actual Results:  
-- CHECK Constraints are not supported in Mysql ( as of version 5.x )
-- But it'll parse the statements without error ALTER TABLE object2 ADD CONSTRAINT object2_object1 FOREIGN KEY (parent) REFERENCES object1 (id);

Expected Results:  
-- CHECK Constraints are not supported in Mysql ( as of version 5.x )
-- But it'll parse the statements without error
ALTER TABLE object2 ADD CONSTRAINT object2_object1 FOREIGN KEY (parent) REFERENCES object1 (id);

This is not a good usecase, but i think that this should be fixed anyway.
