Dear Maintainer,

With the latest releases of pyqt5-sip and pyqt6-sip, I am getting the
following message:

    dmitry@l3:~/python-team/pyqt5-sip (debian/master)$ pristine-tar commit ../pyqt5-sip_12.20.0.orig.tar.gz upstream/12.20.0
    warning: pristine-gz cannot reproduce build of ../pyqt5-sip_12.20.0.orig.tar.gz; storing entire file in delta!
    (Please consider filing a bug report so the delta size can be improved.)
    pristine-tar: committed pyqt5-sip_12.20.0.orig.tar.gz.delta to branch pristine-tar

For pyqt5-sip, it broke between 12.18.0 and 12.19.0. I compared the two files
with diffoscope(1) and I don't see any obvious difference between them.

Here are links to download the files:

12.18.0 (OK): https://files.pythonhosted.org/packages/f3/31/5ef342de9faee0f3801088946ae103db9b9eaeba3d6a64fefd5ce74df244/pyqt5_sip-12.18.0.tar.gz
12.19.0 (broken): https://files.pythonhosted.org/packages/0d/9d/5179b8e619fe084218a87f963f1648cba4c5aa5bb98dd5661d2cbb9eb1e4/pyqt5_sip-12.19.0.tar.gz
12.20.0 (broken): https://files.pythonhosted.org/packages/cd/ab/835df8e6fb06a618a4b8664765c5598e933c8113e90448e294549c9447f7/pyqt5_sip-12.20.0.tar.gz
