# In order to remove individual files:
# http://stackoverflow.com/a/10524661
git filter-branch -f --prune-empty --index-filter "git rm --cached --ignore-unmatch remove1.txt remove2.txt"
# in order to remove history for older files that are no longer part of the repo, find all files that ever existed:
git log --pretty=format: --name-only --diff-filter=A | sort -u
# keep wanted files and remove newlines
git log --pretty=format: --name-only --diff-filter=A | sort -u | grep -v "keep1.txt\|keep2.txt" | tr "\\n" " "
# then feed that list into above command
