Great!

When? It's a disruptive change: Everyone who has patches on top of gnulib
will have to update these. But since we are in continuous development mode
constantly, any time is as good as any other time. (Actually, *before* the
Christmas vacations is better for those of us with little spare time.)

Which set of files? I would say,
  - m4/*.m4          yes
  - lib/**/*.[hcy]   yes except the regex module
    because the regex module is the only major source code for
    which we still have bidirectional propagation between gnulib and glibc,
  - lib/*.charset    no, as it needs a different treatment
  - lib/*.class      no, as it's a binary file
  - modules/*        no, as it contains Makefile snippets

How is this different from "expand -i"? Also, I would try both "expand"
and "expand -i" and look at the differences one by one.
