commit 49618307c14b34414db913cbaa86e1667a3f3797
Author: Michael Heerdegen <michael_heerdegen@web.de>
Commit: Michael Heerdegen <michael_heerdegen@web.de>
[el-search] Make replacement editable and ediff'able
Make the 'el-search-query-replace' replacement editable and ediff'able
using a temporary buffer. Update header comment accordingly.
* packages/el-search/el-search.el (el-search--replace-hunk): Return a
marker pointing to the end of the inserted text.
(el-search-query-replace-ediff-replacement): New function.
(el-search--search-and-replace-pattern): Add and implement keys to
edit the replacement in a separate buffer and to ediff the current
match with the current replacement.

+;; edit the replacement in this buffer. Confirming with C-c C-c will
+;; make el-search replace the current match with this buffer's

+;; (2) At any time you can interrupt a query-replace session by
+;; hitting RET. Make your edits, then resume the query-replace
