The SVN -> Git migration has finished. If you have phpdoc karma, you should
be able to push to the "doc" repos listed on http://git.php.net/ now.

Note that the upstream Git repos are hosted on git.php.net (e.g.
http://git.php.net/?p=doc/en.git;a=summary), but have mirrors on GitHub (
https://github.com/php/doc-en). You should always push changes to the
upstream repo, not the GitHub mirror. The GitHub mirrors only exist to
accept pull requests.

It will take a while for all the tooling to catch up, so in the meantime
some notes on how we typically merge pull requests in php-src:

1. Append ".patch" to the pull request URL:
https://github.com/php/doc-en/pull/293.patch
2. Download the patch: wget
https://patch-diff.githubusercontent.com/raw/php/doc-en/pull/293.patch
3. Apply the patch: git am 293.patch
4. Auto-close the pull request: git commit --am and add "Closes
php/doc-en#293" to the commit message
5. Push: git push origin master

I expect this workflow to be automated for documentation repositories in
the future.
