Copy should make sure destination bitset has enough space

Line 562 in 3821055

copy(c.set, b.set)

c.set could be not large enough to hold the entire b.set

Here is what the function is documented as doing...

// Copy into a destination BitSet using the Go array copy semantics:
// the number of bits copied is the minimum of the number of bits in the current
// BitSet (Len()) and the destination Bitset.
// We return the number of bits copied in the destination BitSet.

If you believe that this behaviour is not followed, please provide a test case.

If you prefer, you can call CopyFull which might what you are looking for.

Closing as "is as intended".
