Forcing quote characters in repr(STRING), how?

Not a clean way, nor even a dirty way:  the logic is hardcoded.

	/* figure out which quote to use; single is preferred */
	quote = '\'';
	if (strchr(op->ob_sval, '\'') && !strchr(op->ob_sval, '"'))
		quote = '"';

IOW,

    quote = "'"
    if "'" in string and '"' not in string:
        quote = '"'

The cleanest way would be to wrap your strings in a subclass of UserString,
and override __repr__ in the subclass.
