Subject: checkout/update boiler plate for --filter-index?
Message-ID: <580660BE-FDAB-4947-B409-1E8D5CBEF8EE@earth.care2.com>

I'm trying to do a historical find-and-replace on my code:

git grep -F foo > files
git filter-branch --index-filter "
   cat `pwd`/files | xargs git checkout  --
   cat `pwd`/files | xargs sed -i 's/foo/bar/g; '
   cat `pwd`/files | xargs git update-index --
" ancestor..HEAD

When I instead use --tree-filter and skip the checkout/update-index,  
it works how I want (but it takes a while...).  But when I use --index- 
filter, the resulting history shows the "foo" to "bar" change  
happening *after* new code is added, rather than originally adding  
"bar".

How can I checkout just a few files and update them to take advantage  
of the speed of index operations?
