bug#17362: 24.4.50; inconsistent key notation: `ESC' vs `<ESC>'

Yes, FWIW, IMO they should be.  But this bug will be fixed if things are
made consistent either way.

Oh, and BTW there are also inconsistencies for those others, including in
nodes: `CUA Bindings', `Misc File Ops', `File Conveniences', `Filesets',
`Speedbar', `Bidirectional Editing', `Other C Commands', `Image Dired',
`Printing Package', `MS-DOS Printing', `Help Mode', `Rectangles', `Special
Isearch', `Regexp Search', `Keyboard Macro Step-Edit', `Marks vs Flags',
`Counting Days', `General Calendar', `HTML Mode', `Windows Keyboard'.

[A related bug?: `<DELETE>' in nodes `Hungry Delete', `MS-DOS Keyboard',
and `Glossary'.  Is `<delete>' what is meant here?  Likewise, you can
find occurrences of `<BACKSPACE>' instead of `<backspace>'.]

And of course there is the way that Emacs itself writes such keys in its
help.  See, e.g., node `International Chars'.  Sometimes Emacs writes
`<RET>' when it communicates with users; sometimes it writes `RET'.

[IMO - but this has been rejected by Emacs Dev more than once - there is 
NEVER any reason to use the angle-bracket notation - it was misguided to
introduce it at all.  And in my own libraries I make it optional whether
Emacs uses angle brackets or not (as far as Lisp is concerned).  For
example, library `naked.el' provides an alternative to `kbd' that lets
you choose the format.  http://www.emacswiki.org/emacs-en/NaKeD,
