a fix (#2185: mysql.server script echo bug)

thnx Paul.                                             
              
<monty> can you get the above into configure and make Makefile.am patch         
mysql.server.sh with the right values for mysql.server ?                        
<monty> or do you think we should just put the above in mysql.server.sh directly
<ramil> as you want                                                             
<monty> the last is kind of hard to do with variables, so lets put the          
above in mysql.server.sh directly
