bug#45536: [PATCH] Pretty-print keys without <> around modifiers

[Drew Adams]

> It is a bit inconsistent that keys are described as C-x and <return> but <C-
> return>. It would be more logical to write C-<return>. The key parser will
> happily accept either, but descriptions without modifiers in <> brackets are
> more legible, and the result is easier to understand and explain.
> 
> Attached is a patch which adapts the code that pretty-prints keys. This is a
> change for human consumption only; it seems unlikely to affect compatibility.
> With the patch, <C-M-backspace> is now printed as C-M-<backspace>.
> 
> I'd be happy to update the manuals accordingly, and add a NEWS entry if
> required.
