r'\' - python parser bug?

[Konstantin Veretennicov]

Many thanks to everyone for enlightening. Now i can see the reasons
behind "no odd number of trailing backslashes" decision.
Maybe they deserve to be appended to FAQ section on raw strings?

Interestingly, C# did it the other way. Trailing backslashes in
verbatim (raw) strings are allowed, but quotes are not:

@"\"   // ok
@"\""  // error, unterminated string literal

For me, personally, trailing backslashes aren't as important as quotes.
Python wins again :)
