Hi thanks for contributing, and thanks for your time!

I'd love to see a Python implementation of the msgcat/poedit wrapping sadly there's not.

If we apply this PR, projects using powrap will be entierly rewrapped (meaning a colossal diff), while powrap is here to lower the diff in project histories by unifying wrapping convention.

I tried on https://github.com/python/python-docs-fr, a powrap *.po */*.po:

$ git diff | wc -l
243576

So no, polib is not an acceptable replacement.

(Yes we really need to stick to msgcat / poedit wrapping as there's a lot of contributors using poedit, so they don't have to care about powrap at all. On the other hand there's nobody editing files with a polib-compatible wrapping convention).

If you're still interested in dropping msgcat dependencies, I started https://github.com/JulienPalard/powrap/tree/from_msgcat that could be a way of doing it.
