It would be nice with Transifex + GitHub to allow generates pull request for locales just like DokuWiki team does.

Eg. https://github.com/dokuwiki-translate/dokuwiki/commit/440b8f2e9d79442f105af80c0302c417b6a6a95e

Process would be:

1. Transifex send hook
2. fetching matching file/locale with tx
3. git diff'ing
4. if new modifications, commit with translator details (name/mail), create a branch “lang_update_xxx”, and do a pull request
