use correct vector/list syntax for keybindings?

use correct vector/list syntax for keybindings?

[Robert Pluim]

In  "(emacs) Init Rebinding", it says

    If a vector element is a character, write it
    as a Lisp character constant: ‘?’ followed by the character as it would
    appear in a string.

There are a fair few bindings in the emacs source that forget the '?'
and do eg

    [(control c)]

Is it worth going through and changing those?

This is not the syntax the text above is talking about.  It is a vector
of Lucid-style event type lists, where the characters can be written as
symbols (see event-convert-list).  It is supported for XEmacs
compatibility.

The elisp manual makes it clear that the intended syntax for single
characters is the same in both cases. In "(elisp) Changing Key
Bindings":

       The key definition and lookup functions accept an alternate syntax
    for event types in a key sequence that is a vector: you can use a list
    containing modifier names plus one base event (a character or function
    key name).  For example, ‘(control ?a)’ is equivalent to ‘?\C-a’ and
    ‘(hyper control left)’ is equivalent to ‘C-H-left’.

The support for base characters written as symbols is present almost
since the beginning.
