Dumpgenerator.py completes but dump fails the grep check.

Windows 10, Git Bash, python3 branch. The XML dump is mostly a single and far too long line. It fails the check by grep mentioned in the Wikiteam tutorial and passes when using --curonly instead of --xmlrevisions.
$ dumpgenerator --failfast --xml --xmlrevisions --api=https://sdiywiki.miraheze.org/w/api.php
Checking API... https://sdiywiki.miraheze.org/w/api.php
API is OK: https://sdiywiki.miraheze.org/w/api.php
Checking index.php... https://sdiywiki.miraheze.org/w/index.php
index.php is OK
No --path argument provided. Defaulting to:
  [working_directory]/[domain_prefix]-[date]-wikidump
Which expands to:
  ./sdiywikimirahezeorg_w-20221215-wikidump
--delay is the default value of 0.5
There will be a 0.5 second delay between HTTP calls in order to keep the server from timing you out.
If you know that this is unnecessary, you can manually specify '--delay 0.0'.
