Do backslashes also need to be backslashed then?  If not, then what is 
the translation of this:?

     r'abc\{%s\}' % 'x'

I guess the only sensible translation if backslashes aren't backslashed 
would be:

     r'abc\\{{0}\\}'.format('x')

But the parsing of that format string seems fairly unintuitive to me. 
If backslashes do need to be backslashed, then that fact needs to be 
mentioned.
