bug#13313: 24.2; typo in the document string of query-replace-regexp

[Jeova Sanctus Unus]

the docstring of query-replace-regexp says:
Replacement transfers the case pattern of the old text to the new
text, if `case-replace' and `case-fold-search' are non-nil and REGEXP
has no uppercase letters.

but 15.9.3 Replace Commands and Case says:
Likewise, if either `case-replace' or `case-fold-search' is set to
`nil', replacement is done without case conversion.

>From the experience of using query-replace-regexp,I  suppose the
docstring of query-replace-regexp is wrong: the 'and` should be 'or`
