but sync RCS IDs for easier future adaption:
* Simplify savefd() by removing the "noclose" flag and make noclose
  behavior the default. Almost all uses of savefd() are followed
  by an implicit or explicit close.
* fix typos
* might as well make ksh_getopt() match real getopt(), ie. get rid of that
  stupid EOF concept that was never true. adobriyan@gmail
* use SEEK_* for lseek()
* fix lint comments, no functional changes
* remove excessive optimization; from adobriyan@gmail
* only santa checks things twice; from adobriyan@gmail
* Interpret zero-filled numbers as decimal; PR 4213; from Alexey Dobriyan
