The files below "mysql-test/suite/funcs_1" in version 5.1
did not depend on the equivalent ones in 5.0,
probably because they had been checked in independent of each other
in both versions.

Step 1:
Foreach file F in the suite that has a "deleted" counterpart D, use
    bk rm $F
    bk mv $D $F
to get those files into the 5.1 suite that (for BK) depend on 5.0.
