Additional changes needed to backport:
- dropped legacy SVN support from patchcheck
- use subprocess.PIPE to silence expected error output
- don't try to use subprocess.Popen as a context manager
- don't try to pass a keyword argument to str.split()
(cherry picked from commit 482f7a274f)
The line about the test suite will still get printed for changes in
Tools for example, which aren’t covered by the test suite, but it’s not
a big deal IMO.
some verification:
- Runs reindent.py on all .py files.
- Checks if any changes in Doc exist.
- Whether Misc/ACKS was changed.
- Whether Misc/NEWS was changed.
The hope is that ``make check`` can become a command anybody can run to get
reminders about what all the requisite steps needed to create a proper
patch/checkin.
