maint: convert all TABs to equivalent spaces in indentation

Using this file,

cat > leading-blank.exempt <<\EOF
(\.gitmodules|help2man|pre-commit)$
(?:^|\/)ChangeLog[^/]*$
(?:^|\/)(?:GNU)?[Mm]akefile[^/]*$
\.(?:am|mk)$
EOF

run the following command to convert all non-conforming leading white
space to be all spaces:

git ls-files \
  | pcregrep -vf leading-blank.exempt \
  | xargs pcregrep -l '^ *\t' \
  | xargs perl -MText::Tabs -ni -le \
    '$m=/^( *\t[ \t]*)(.*)/; print $m ? expand($1) . $2 : $_'

Since that changed old NEWS, I also ran "make update-NEWS-hash"
to update the old_NEWS_hash value in cfg.mk.
