A backslash in a double-quoted string is handled by backslash-substitution,
before it is ever seen as a regexp. "\'" is exactly the same as "'".
In a braced string it does not get backslash-substitution and then it _is_
handled by the regular expression parsing, but again, as RE {\'} is exactly
the same as {'}.
