* replace.el (query-replace-highlight): Add new value `isearch'

that allows query replacement to use isearch highlighting.
Change type from `boolean' to `choice'.  Doc fix.
(replace-highlight, replace-dehighlight, perform-replace):
Use isearch highlighting if query-replace-highlight eq `isearch'.

+       * isearch.el (isearch-edit-string): Set 7th arg of
+       `read-from-minibuffer' to `t' to inherit the current input
+       method (whose name is indicated by [IM] in the minibuffer prompt)
+       from the current buffer to the minibuffer.
+       (isearch-lazy-highlight-update): Put body to `with-local-quit'
+       to allow C-g quitting for lazy highlighting looping inside the
+       search with nested repetition operators.  Add overlay to the list
+       before setting its face and other properties to avoid the case of
+       code quitting after placing the new overlay but before it's
+       recorded on the list.  Select the window where isearch was
+       activated, to highlight matches in the right window when isearch
+       switches the current window to the minibuffer.
+
+       * international/isearch-x.el
+       (isearch-process-search-multibyte-characters):
+       Use `isearch-message' as initial input for `read-string' instead
+       of adding it to the minibuffer prompt.  After reading a string
+       remove the initial value of `isearch-message' from the string.
+
+       * replace.el (replace-match-maybe-edit): Doc fix.
+       (perform-replace): Don't call `replace-highlight' when automatic
+       replacement is requested in literal mode, since it is intended
+       only to highlight words during entering a new replacement string
+       for \? in non-literal mode.
+
+       * replace.el (query-replace-highlight): Add new value `isearch'
+       that allows query replacement to use isearch highlighting.
+       Change type from `boolean' to `choice'.  Doc fix.
+       (replace-highlight, replace-dehighlight, perform-replace):
