Thanks for doing this (tedious work)!

There are a few nits, though:
  * http://www.w3.org/TR/html401/loose.dtd is not a URL; it's a declaration.[1]
    I fear that the change to https makes the resulting documentation display
    worse in some browsers.
    This affects build-aux/pmccabe2html and doc/gendocs_template_min.
  * I don't find it adequate to remove comments in
      lib/creat.c
      lib/fopen.c
      lib/open.c
      lib/openat.c
      tests/test-fflush2.c
    I mean, just pointing to a 13-page long document
      https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html
    as a rationale for some small technical decision really obscures the
    technical argument.
  * What happened to point 3 in lib/fflush.c?
