Thanks for the feedback!

I am trying to prevent exactly what you described. git-filter-repo
needs Python >=3.5 to function and we know that `/usr/bin/python3` is
the correct version. Suppose a user installed Python 3.3 at
`/usr/local/bin/python3`, now git-filter-repo will run with the wrong
Python version and most likely break. This is what other distributions
do when they distribute Python scripts and I'm fairly sure Debian
explicitly calls this out in its policy.

Yeah the patch file was automatically generated when I ran `cygport
all` and I wasn't sure what to do with it. To me it seems silly to
have a patch just to change the shebang line when `sed` works fine.
I'll try removing `sed` to see what happens.

Yeah I initially didn't have it in the Python category, but then I
thought about how other tools like bzr and mercurial are there so it
seemed appropriate. Granted I didn't check if they also provided
Python libraries, but I thought it made sense to put git-filter-repo
in the Python category to maybe warn users that installing it would
pull in Python.

I wasn't sure how to go about this since I didn't know if that would
mean making a bunch of 'python3*-git-filter-repo' packages.
Do you think I should make it importable, remove it from the Python
category, or just leave it as is?

Since git-filter-repo is a third-party command like git-lfs, I am of
the opinion that it should go in `/usr/bin` rather than git's private
`libexec`. That's also how Debian, Gentoo, Arch, and Homebrew package
it. Also I believe my cygport file does pretty much follow the manual
installation instructions except for the part about installing
git_filter_repo.py (for the reasons I stated above). I would like to
use the Makefile, however it has a number of things that make it
difficult to work with in this context and from what I've seen
basically none of the other packagers use it and instead opt to do the
installation manually like I have.

I'll add that in. The package does currently report some errors with
git 2.35 and it has been reported upstream (not by me)
I look forward to getting this in Cygwin!
