If a "=" is specified a the end of an f-string expression, the f-string will evaluate to the text of the expression, followed by '=', followed by the repr of the value of the expression.

Add an additional test with a newline, one that's very similar to test_parens_in_expressions, but because the newline is not a literal newline, but a backslash en, this error is triggered.

Move f-string compilation of the expression earlier, before the conversion character and format_spec are checked. This allows for error messages that more closely match what a user would expect.
