SRFI 178 was finalized recently, but Shiro Kawai noticed that a bunch of corrections that had been discussed on the mailing list somehow hadn't made it into the final draft.  John has included them now, and has sent these notes to describe them:
  1. (most important) The vector->bitvector and reverse-vector-bitvector procedures were intended to accept optional start and end arguments like all the other conversion functions (except conversions from lists), but these arguments were left out of the SRFI.
  2. Clarify that bitvector-prefix-length, bitvector-suffix-length, bitvector-prefix?, bitvector-suffix? do not require their arguments to be of the same length.
  3. make-bitvector-accumulator does not take an argument, because no SRFI 158 accumulator constructor does; you call one, get an empty accumulator, and load it with values. It is generator constructors that take arguments.
  4. The definition of bitvector-field-rotate speaks of high-order bits, an undefined term in this SRFI. Changed to speak of bits with lower indices.
  5. Clean up formatting of the conversion procedures so they all look the same.
I've tagged this version as final.1 in Git.

Thanks to Shiro.
