-- Rename/redefine integral types -- Ben Wing
   -- See src/ChangeLog for details and rationale.
   -- All integral types that measure quantities of anything are signed.
   -- All quantity types boil down to EMACS_INT, except Hashcode,
      which is an unsigned value of the same size as EMACS_INT.
   -- Type names should be relatively short, with the first letter
      capitalized and no underscores if they can be avoided.
   -- "*count" == zero-based quantity.  Includes sizes, offsets, and indexes.
   -- "*bpos" == one-based buffer position.
   -- "Char" refers to internal-format characters, not to the C type "char".
