Perhaps the Python documentation could use some clarification about
when the platform's convention is required and when it isn't.
The "Embedding Python" documentation shows embedded code with lines
ending in \n and without saying anything about requiring the
platform's convention:

That the behavior makes life simpler is an argument against it being
broken (although it would be even less broken if it were more
flexible about what line endings it allows). A detailed response
would be getting off-topic for PostgreSQL, but I'll stand by what
I said earlier: I would find it bizarre if embedded Python code had
to use different line endings on different platforms. That would
mean the programmer couldn't simply do this:
PyRun_SimpleString("x = 1\n"
"print x\n");
Instead, the programmer would have to do a compile-time or run-time
check and build the string in a platform-dependent manner. What
problem would the language be solving by requiring that?
