| | | | Due to backwards compatibility concerns regarding keywords immediately followed by a string without whitespace between them (like in `bg="#d00" if clear else"#fca"`) will fail to parse, commit 41d5b94af44e34ac05d4cd57460ed104ccf96628 has to be reverted.

* bpo-40267: Fix message when last input character produces a SyntaxError ↵Lysandros Nikolaou2020-04-151-1/+1
| | | | | | | | (GH-19521) When there is a SyntaxError after reading the last input character from the tokenizer and if no newline follows it, the error message used to be `unexpected EOF while parsing`, which is wrong.

| | | | | | | | | | | | | | | | | | DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals just as it did in 3.7. SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner. (Applies 4c5b6bac2408f879231c7cd38d67657dd4804e7c to the master branch).

* Add an additional test with a newline, one that's very similar to ↵Jason R. Coombs2016-11-061-0/+1
