I would be happy to do that to all of gnulib.
It is long overdue.

I've used this shell function to convert other projects:

no-tabs-for-indentation()
{
  local exclude=/dev/null
  local x2=.x-sc_TAB_in_indentation
  test -f $x2 && exclude=$x2
  git ls-files \
    | pcregrep -vf $exclude \
    | xargs pcregrep -l '^ *\t' \
    | xargs perl -MText::Tabs -ni -le \
      '$m=/^( *\t[ \t]*)(.*)/; print $m ? expand($1) . $2 : $_'
}

If everyone agrees, I'd like to update copyrights, too,
before the new year.
