Global changes
--------------

-  Build system:
   -  Add scripts to produce a book of the Linux man-pages.
   -  Add lint-c-cppcheck to the make(1) targets to run the cppcheck(1)
      linter.

-  TH:
   -  Use correct letter case in page titles.  This started in 6.02, but
      there were still many cases left.

-  SYNOPSIS:
   -  Mark some functions as deprecated.

-  STANDARDS:
   -  Remove most references to ISO C89.  We still document it in
      standards(7), but it's an ancient language version that this
      project
      regards as obsolescent, so in the STANDARDS sections for APIs we
      only take into account C99 and later and POSIX.1-2001 and later
      (with few exceptions where older standards are relevant).

-  ffix:
   -  Change \- to - where appropriate
   -  Improve readability of numbers:
      -  Show BCD magic numbers that are meaningful in hex as hex,
         rather than weird decimal numbers.
      -  Use IEC multipliers.
   -  Format ranges consistently using interval notation: [min, max].

-  srcfix:
   -  Use \[] escapes.
