Subject: convert all TABs to equivalent spaces in indentation

Using this file,

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

run this 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 : $_'
