The variable name ret sounds like the variable to be returned, but
since e6c111b4 we return error. Hence the variable name is miss leading.
As this variable is used only to extract the bits from the callback of
a tree object, I named it cb_bits for callback bits.
Also the assignment to 0 was removed at the start of the function as well
after the if(interesting) block. Those were unneeded as that variable
is set to the callback return value any time we enter the if(interesting)
block, so we'd overwrite old values anyway.
