[Python-Dev] Emit SyntaxWarning on unrecognized backslash escapes?

[Serhiy Storchaka]

See topic "Unrecognized backslash escapes in string literals" in Python 
list [1]. I agree that this is a problem, especially for novices (but 
even experience users can make a typo). May be emit SyntaxWarning on 
unrecognized backslash escapes? An exception is already raised on 
invalid octal or hexadecimal escapes. '\x' is syntax error, not two 
characters '\\' and 'x'.
