Branching of "raw" allows to maintain the optimization introduced in #29260 while supporting this edge case. Regression in 85458e94e38c20e57939947ee515a1a53689659f. Thanks Reupen Shah for the report.

Django
Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out.
All documentation is in the "docs
" directory and online
at https://docs.djangoproject.com/en/stable/.
If you're just getting started, here's how we recommend you read the
docs:
- First, read
docs/intro/install.txt
for instructions on installing Django. - Next, work through the tutorials in order
(
docs/intro/tutorial01.txt
,docs/intro/tutorial02.txt
, etc.). - If you want to set up an actual deployment server, read
docs/howto/deployment/index.txt
for instructions. - You'll probably want to read through the topical guides (in
docs/topics
) next; from there you can jump to the HOWTOs (indocs/howto
) for specific problems, and check out the reference (docs/ref
) for gory details. - See
docs/README
for instructions on building an HTML version of the docs.
Docs are updated rigorously. If you find any problems in the docs, or think they should be clarified in any way, please take 30 seconds to fill out a ticket here: https://code.djangoproject.com/newticket
