* doc/regexp.rdoc: In regexp doc, two backslashes match one literally
In the "Metacharacters and Escapes" section of regexp.rdoc, it said that
to match a backslash literally, it must be backslash-escaped, but the
rendered HTML showed three backslashes (\\\). There should only be two
backslashes (\\).
