Das ist Quatsch!  The user simply wanted the section of music before the 
repeated section to end with a double bar.  He didn't want the opening 
repeat-sign  to be suppressed.  :(

Why shouldn't it be changed to work like the 99% would like?  Let those who 
want the current behavior use, say, \bar "~://?" to indicate that they don't 
want the usual opening repeat-sign to appear.  The others don't want to delve 
into the arcana of the various bar signs.  They just want the section before a 
repeat section to end with a double-bar.
