This is in the way of adding an inline member-swap() (can't take references to bit-fields), and therefore move-assignment. We can always redistribute the bits in freeBuffer later, if needed: there are (and, since 6.0, were) no inline users of this member. This should even improve codegen, as the compiler doesn't have to deal with bit-fields anymore. There's no need to pessimize the code for that kind of flexibility until another user actually surfaces. Amends the start of the public history.
