bug#13348: 24.3.50; `C-s', `C-r', `RET' in `minibuffer-local-isearch-map'

["Drew Adams" <drew.adams@oracle.com>]

`M-e' in Isearch is `isearch-edit-string'.  Here is its doc:
 
  Edit the search string in the minibuffer.
  The following additional command keys are active while editing.
 
  M-x exit-minibuffer to resume incremental searching with the edited string.
  RET to do one nonincremental search.
  C-s to resume isearching forward.
  C-r to resume isearching backward.
  C-M-i to complete the search string using the search ring.
  C-x 8 RET to insert a Unicode character by name (with completion).
 
  If first char entered is C-w, then do word search instead.
 
Now do this: `C-s M-e C-h k C-s'.  You see this:
 
  C-s runs the command isearch-forward-exit-minibuffer, which is an
  interactive compiled Lisp function in `isearch.el'.
 
  It is bound to C-s.
 
  (isearch-forward-exit-minibuffer)
 
  Not documented.
 
Not documented?  Why not?  Emacs users deserve better.
 
These commands (for keys `C-s', `C-r', `RET') are explicitly called out
in the doc for `isearch-edit-string'.  They should have doc strings.
`C-M-i' (`isearch-complete-edit') does, and so should all of the other
keys mentioned in the doc of `isearch-edit-string'.
