	* gdb.base/break.exp: Remove commented out if $usestubs {}.  As
	nearly as I can tell, the whole thing was an accident in Stu's
	change of 24 Mar 1995 (logged in ../ChangeLog), in which he meant
	to replace a send/expect pair with gdb_test, but ended up only
	adding the gdb_test.  My change of 24 Mar 1995 and Kung's change
	of 30 Mar 1995 took care of it, but left this vestigial comment
	which I am now nuking.
