Well, you need
git filter-branch --tag-name-filter=cat --tree-filter=' ... '
encantation where the elided shell script actually updates all your
files. That script runs in the work tree for each commit on the branch
you're rewriting and typically employs applying some text transformation
for all the files in the work tree which are of interest.
* `git filter-branch` only rewrites branches.
AFAIK, there's no way to re-write "all commits" in a single run.
* The "--tag-name-filter=cat" is needed to re-create tags pointing
to the rewritten commits of a branch being operated upon.
* Tags can be re-written individually using a simple script.
You might also look at a 3rd-party tool  but I personally have no
experience with it.
