Terminal and event-apply-control-modifier

[Michael Brand]

Hi all

I have an understanding problem with ~event-apply-*-modifier~. Are the
following differences ~<C-return>~ vs. ~C-RET~ and ~<S-return>~ vs.
~RET~ between GUI and terminal intentional?

~C-h c C-x @ c <RET>~ in a GUI shows
#+begin_example
<C-return> (translated from C-x @ c) runs the command
org-insert-heading-respect-content
#+end_example
but in a terminal (-nw) it shows
#+begin_example
C-RET (translated from C-x @ c) is undefined
#+end_example
where I expect the same result.

~C-h c C-x @ S <RET>~ in a GUI shows
#+begin_example
<S-return> (translated from C-x @ S) runs the command org-table-copy-down
#+end_example
but in a terminal it shows
#+begin_example
RET (translated from C-x @ S) runs the command org-return
#+end_example
where I expect the same result.

I tried Emacs 26.1 and 25.2 in Gnome Terminal and iTerm2 on GNU/Linux and macOS.
