 -A significantly faster version:
 +Using `\--index-filter` with 'git-rm' yields a significantly faster
 +version.  Like with using `rm filename`, `git rm --cached filename`
 +will fail if the file is absent from the tree of a commit.  If you
 +want to "completely forget" a file, it does not matter when it entered
 +history, so we also add `\--ignore-unmatch`:
  
  --------------------------------------------------------------------------
 -git filter-branch --index-filter 'git rm --cached filename' HEAD
 +git filter-branch --index-filter 'git rm --cached --ignore-unmatch filename' HEAD
  --------------------------------------------------------------------------
  
  Now, you will get the rewritten history saved in HEAD.
  
 -As with using `rm filename`, `git rm --cached filename` will fail
 -if the file is absent from the tree of a commit.  If it is not important
 -whether the file is already absent from the tree, you can use
 -`git rm --cached --ignore-unmatch filename` instead.
