I'd contend that the two primary purposes of raw strings (this is
starting to sound like a Spanish Inquisition sketch) are regexes and
DOS/Win32 file path literals.  And I hit this trailing-backslash case
all the time, as Vim's path-completion defaults to putting the
trailing backslash at the end.  So I might be entering a literal like

  r"c:\win

and hit <tab> which expands to

  r"c:\Windows\

for which I then need to both remove the backslash and close the
quote.  If Python's parser just blithely ignored terminal
backslashes, I could just close the quote and get on with my day.
