Severity: wishlist

In (info "(elisp) Other Char Bits"), I read:

    Emacs uses the 2**25 bit to indicate that the shift key
    was used in typing a control character.  This distinction is possible
    only when you use X terminals or other special terminals; ordinary text
    terminals do not report the distinction.

Can we change "when you use X terminals or other special terminals" to
"on a graphical display"?

See the attached patch that also fixes some other similar cases.
